To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

首頁| 登錄| 現在註冊 [2009年07月29日]關鍵字：電壓位準轉換記憶卡處理器隨著可攜式產品的功能日益豐富，體積又不斷縮小，耗電量已成為產品設計必須管理的重要課題。
由於製程技術進步，設計人員已能使用操作電壓更低的新型處理器，但這也造成系統中可能出現多種不同的電壓。
舉例來說，儘管某些處理器已將其最大I/O電壓限制為1.8V，許多週邊裝置卻仍採用傳統的3.3V操作電壓。
由於目前多數可卸除式flash記憶卡大都用於操作電壓3V的可攜式產品上，低電壓處理器和記憶卡的操作電壓不同情形也會發生，所以兩者之間必須以電壓位準轉換器做為連接介面，才能互相傳送資料。
處理器與SD/SDIO記憶卡過去都使用同樣的電壓，兩者之間的介面如圖1所示。
SDIO介面包含4個資料訊號(DA T0-3)、1個時脈訊號(CLK)和1個命令訊號(CMD)，其中資料和命令訊號都是雙向訊號，時脈訊號則為單向訊號。
記憶卡連接器通常包含機械式防寫保護(Write Protect，WP)與記憶卡偵測(Card Detect，CD)開關，處理器會利用回傳的WP和CD訊號，來達到如啟動電路板某些控制功能。
為了避免資料訊號與命令線路進入浮動狀態，這些線路都必須連接一個上拉電阻到VDD。
主流電壓位準轉換器隨著處理器和SDIO週邊的介面操作電壓出現差異，現在必須加入電壓位準轉換器，確保開關切換的相容性。
目前已有數種方法可提供適當的電壓位準轉換，實際選擇視應用環境而定。
舉例來說，系統設計人員可選擇不同的電壓位準轉換解決方案，以便控制資料與命令訊號在處理器與記憶卡之間的雙向傳送方式：採用具有方向控制接腳的電位轉換收發器，或者使用無方向性的電壓位準轉換器。
這兩者都是可行方案，各有其優缺點。
1. 具有方向控制接腳的電壓位準轉換器：圖2是具有方向控制接腳的雙向電壓位準轉換器，又稱為完全緩衝式(fully buffered)電壓位準轉換器。
其輸出電晶體通常能提供數十個mA的直流電流，資料速率只受輸出電容性負載和電晶體開關速度的限制。

TROUBLESHOOTING1. No Video:• Ensure the power switch is on.• Confirm that the correct source is routed to the correct output.• Confirm that the source is powered on and connected to the correct input.• Confirm that the source is outputting a signal (using the Source Status LED)on the front of the unit.• Confirm the TV is on the correct input.2. Poor Video (hum bars in picture, picture distortion, noise in picture)• The #1 cause of poor video quality is low-quality interconnects. Never use theinterconnect cables that are included with DVD players, cable boxes, etc, as theyare very susceptible to EMI and noise. We highly recommend using Binary™ Cables, which are designed for this application.• Confirm that the source is outputting video at the correct levels. You can try to bypass the switcher and connect the display directly to the source and confirm the source is outputting a clean signal• Confirm that the connections between the TV and the switcher are good.• If using a Balun, confirm that the CAT-5 is terminated with TIA-568b standards onboth sides. You can also bypass the switcher by connecting the source directly tothe Balun to ensure the noise is not an interference issue with the CAT5 or the Balun.• Confirm that the power for the switcher and source gear is clean and is not sharing a circuit with noisy devices (ceiling fans, refrigerators, florescent lights, etc)• Some homes that do not have adequate grounding can have ground loops between different circuits. In these cases, you can try to use a ground lift at the TV to eliminate ground loop issues that can create noise in Video.IR REMOTE CONTROL1. DISCRETE POWER ON2. DISCRETE POWER OFF3.

DESCRIPTION/ORDERING INFORMATION
This 8-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB.
