2015款 27吋Retina 5K iMac MK472(中配)升级M.2 MVMe SSD + SATA 3 SSD

胆⼤⼼细，2015款 27吋Retina 5K iMac MK472（中配）升级M.2 NVMe SSD + SATA 3 SSD·CZCZYX·⼀、目标2016年购入2015款 27吋Retina 5K iMac MK472（中配），原配256G SATA-e SSD，无机械硬盘，买了AC，未发生过故障。

购机后就自己增加过16G内存（共24G）。

平时喜欢折腾，经常感觉SSD容量太小，捉襟见肘。

很早就萌生了升级M.2 NVMe SSD的想法。

好不容易捱过了保修期，就做了些准备，开始动手了。

折腾的目标是把原配的SSD换成M.2 NVMe 1T SSD，一是增加了容量，二是体验NVMe 的高速。

另外，既然拆机了，就顺便在原机械硬盘位添加一块SATA3 1T SSD。

至于CPU就不升级了，感觉无此必要。

⼆、我准备的器材和⼯具1、970 Pro 1TB V-NAND 2bit MLC SSD一块2、1TB 3D Nand 2.5 Inch SATA III SSD一块3、适用于2012及更新款的27吋iMac HDD升级套件，包括：（1）HDD升级用串联数字温度热传感器电缆（不包括SATA III数据/电源电缆）（2）iMac屏幕拆卸专用滚轮（3）OEM屏幕胶条（4）屏幕玻璃吸盘2只（5）T8S、T10S螺丝起子各一把（6）撬棒（7）清洁布4、适用于2015年27吋A1419 iMac的 SATA III 硬盘数据/电源线一套5、M.2 NVMe SSD 2280转接卡一块（长卡），M2.5x8螺丝一只，M2.5垫片一片（说明：网购的转接卡一般只配M2x6螺丝一只，无法用于iMac）6、M.2 固态硬盘2280散热片（2~3mm厚纯紫铜质最好）及导热硅胶垫片、橡皮筋一套7、2.5吋转3.5吋硬盘金属托架一块，M3x5螺丝4只8、M3x8螺丝4只；直径约4.5mm的废圆珠笔芯塑料管，剪成每段约2mm长的4段（自制硬盘金属托架固定螺丝用）9、T5、T20螺丝起子各一把（我是用的以前网购的组合套件）10、直径2mm十字螺丝刀一支11、重要！一个macOS系统安装U盘。

The modem and a few external passive components provide all of the functions needed to satisfy HART physical layer requirements including modulation, demodulation, receive filtering, carrier detect and transmit-signal shaping. The HT2015 is pin-compatible with theSYM20C15. See the Pin Description and Functional Description sections for details on pin compatibility with the SYM20C15.The HT2015 uses Phase Continuous Frequency Shift Keying (FSK) at 1200 bits per second. To conserve power the receive circuits are disabled during transmit operations and vice versa.

See IAREF in DC Characteristics on page 11.ICDREF: Carrier Detect Reference VoltageThis analog input controls at which level the carrier detect (OCD) becomes active. This is determined by the dc voltage difference between ICDREF and IAREF. Selecting ICDREF - IAREF equal to 0.08 V DC will set the carrier detect to a nominal 100 mV p-p.INRESET: Reset Digital LogicWhen at logic low (V SS) this input holds all the digital logic in Reset. During normal operation INRESET should be at V DD. INRESET should be held low for a minimum of 10 nS after V DD = 2.5 V as shown in Figure 3.INRTS: Request To SendThis active-low input selects the operation of the modulator. OTXA is enabled when this signal is low. This signal must be held high during power-up.IRXA*: Analog Receive InputThis input accepts the 1200/2200 Hz signals from the external filter. IRXAC: Analog Receive Comparator InputThis is the positive input of the carrier detect comparator and the receiver filter comparator.ITXD: Digital Transmit Input (CMOS) This input to the modulator accepts digital data in NRZ form. When ITXD is low, the modulator output frequency is 2200 Hz. When ITXD is high, the modulator output frequency is 1200 Hz.IXTL: Oscillator InputThis input to the internal oscillator must be connected to a parallel mode 460.8 kHz ceramic resonator when using the internal oscillator or grounded when using an external 460.8 kHz clock signal. OCBIAS: Comparator Bias CurrentThe current through this output controls the operating parameters of the internal operational amplifiers and comparators. For normal operation, OCBIAS current is set to 2.5 4A.OCD: Carrier Detect OutputThis output goes high when a valid input is recognized on IRXA. If the received signal is greater than the threshold specified on ICDREF for four cycles of the IRXA signal,the valid input is recognized. Figure 3 - Reset TimingO RXAF*: Analog Receive Filter OutputThis signal is the square wave output of the receiver high-pass filter.ORXD: Digital Receive Output (CMOS) This signal outputs the digital receive data. When the received signal (IRXA) is 1200 Hz, ORXD outputs logic high. When the received signal (IRXA) is 2200 Hz, ORXD outputs logic low. ORXD is qualified internally with OCD and is logic high when OCD is low.OTXA: Analog Transmit OutputThis output provides the trapezoidal signal controlled by ITXD. When ITXD is low, the output frequency is 2200 Hz. When ITXD is high, the output frequency is 1200 Hz. This output is active when INRTS is low and 0.5 V DC when INRTS is high. OXTL: Oscillator OutputThis output from the internal oscillator must be connected to an external 460.8 kHz clock signal or to a parallel mode 460.8 kHz ceramic resonator when using the internal oscillator. TEST(12:1): Factory TestThese are factory test pins. For normal operation, tie these signals as per Table 1.VDD: Digital PowerThis is the power for the digital modem circuitry.VDDA: Analog Supply VoltageThis is the power for the analog modem circuitry.VSS: GroundThis is the analog and digital ground. VSSA: Analog GroundThe HT2015 is a functional equivalent of the SYM20C15 HART Modem. It contains a transmit data modulator and signal shaper, carrier detect circuitry, analog receiver and demodulator circuitry and an oscillator, as shown in Figure 4.The internal HART modem modulates the transmit-signal and demodulates the receive signal. The transmit-signal shaper enables theHT2015 to transmit a HART compliant signal. The carrier is detected by comparing the receiver filter output with the difference between two external voltage references. The analog receive circuitry band-pass filters the received signal for input to the modem and the carrier detect circuitry. The oscillator provides the modem with a stable time base using either a simple external resonator or an external clock source.Functional DescriptionFigure 4 - HT2015 Block DiagramHT2015 LOGIC The modem consists of a modulator and demodulator. The modem uses shift frequencies of nominally 1200 Hz (for a 1) and 2200 Hz (for a 0). The bit rate is1200 bits/second.Modulator The modulator accepts digital data in NRZ form at the ITXD input and generates the FSK modulated signal at the OTXA output. INRTS must be a logic low for the modulator to be active.Demodulator The demodulator accepts an FSK signal at the IRXA input and reproduces the original modulating signal at the ORXD output. Thenominal bit rate is 1200 bits per second. Figure 5 illustrates the demodulation process. The output of the demodulator is qualified with the carrier detect signal (OCD), therefore, only IRXA signals large enough to be detected (100 mVp-p typically) by the carrier detect circuit produce received serial data at ORXD. Maximum demodulator jitter is 12 percent of one bit given input frequencies within HARTspecifications, a clock frequency of 460.8 kHz (±1.0 percent) and zero input (IRXA) asymmetry.Modem CharacteristicsFigure 5: Demodulator Signal TimingTRANSMIT–SIGNAL SHAPER The transmit-signal shaper generates a HART compliant FSKmodulated signal at OTXA. Figure 6 and Figure 7 show the transmit-signal forms of the HT2015. For IAREF = 1.235 V DC , OTXA will have a voltage swing from approximately 0.25 to 0.75 V DC .CARRIER DETECT CIRCUITRY The Carrier Detect Comparator shown in Figure 8 below generates logic low output if the IRXAC voltage is belowICDREF. The comparator output is fed into a carrier detect block (see Figure 4 on page 5). The carrier detect block drives the carrier detect output pin OCD high if INRTS is high and four consecutive pulses out of thecomparator have arrived. OCD stays high as long as INRTS is high and the next comparator pulse is received in less than 2.5 ms. Once OCD goesinactive, it takes four consecutive pulses out of the comparator to assert OCD again. Four consecutive pulses amount to 3.33 ms when the received signal is 1200 Hz and to 1.82 ms when the received signal is 2200 HZ.Figure 7 - OTXA Waveform (2200 Hz)Figure 6 - OTXA Waveform (1200 Hz)ANALOG RECEIVER CIRCUITRYVoltage References The HT2015 requires two voltage references, IAREF and ICDREF. IAREF sets the dc operating point of the internal operational amplifiers and comparators. A 1.235 V DC reference (Analog Devices AD589) is suitable as IAREF. The level at which OCD (carrier detect) becomes active is determined by the dc voltage difference (ICDREF - IAREF). Selecting a voltage difference of 0.08 V DC will set the carrier detect to a nominal 100 mV p-p .Bias Current Resistor The HT2015 requires a bias current resistor to beconnected between OCBIAS and V SS . The bias current controls the operating parameters of the internal operational amplifiers and comparators. The value of the bias current resistor is determined by the referencevoltage IAREF and the following formula:The recommended bias current resistor is 500 ohm; when IAREF is equal to 1.235 V DC . In Figure 8 all external capacitor values have a tolerance of ±5 percent and the resistors have a tolerance of ±1 percent, except the 3 ohm; which has a tolerance of ±5 percent. External to the HT2015, the filter exhibits a three-pole, high-pass filter at 624 Hz and a one-pole, low-pass filter at 2500 Hz.Internally, the HT2015 has a high-pass pole at 35 Hz and a low-pass pole at 90 kHz. The low-pass pole can vary as much as ±30 percent. The inputimpedance of the entire filter is greater than 150 ohm; at frequencies below 50 kHz.Figure 8 - Receive Filter SchematicR BIAS =OSCILLATOR The HT2015 requires a 460.8 kHz clock signal on OXTL. This can be provided by an external clock or external components may be connected to the HT2015 internal oscillator.Internal Oscillator Option The oscillator cell will function with either a 460.8 kHz crystal orceramic resonator. A parallel resonant ceramic resonator can be connected between OXTL and IXTL. Figure 9 illustrates the crystal option for clock generation using a 460.8 kHz (±I percent tolerance) parallel resonant crystal and two tuning capacitors. The actual values of the capacitors maydepend on the recommendations of the manufacturer of the resonator. Typically, capacitors in the range of 100 pF to 470 pF are used.External Clock Option It may be desirable to use an external 460.8 kHz clock as shown in Figure 10 rather than the internaloscillator because of the high cost and low availability of ceramic resonators. In addition, the HT2015 consumes less current when an external clock is used. Minimum current consumption occurs with the clock connected to OXTL and IXTL connected to V SS .Figure 10 -Oscillator with External ClockFigure 9 - Crystal OscillatorElectrical CharacteristicsT A Ambient -40 CABSOLUTE MAXIMUMS+85 T S Storage Temperature -55 150 CV DD Supply Voltage - .3 6.0 VV IN , V OUT DC Input, Output - .3 V DD + .3 VT L Lead Temperature (soldering) 250 CCautions:1.
