Connect to GND. 2, 3 SDI, SDI Analog Input Serial digital differential input. 5, 6 AGC, AGC Analog – External AGC capacitor. Connect pin 5 and pin 6 together as shown in the GS1674 Typical Application Circuit on page 11. 7BYPASS Not Synchronous Input Forces the Equalizing and DC RESTORE stages into bypass mode when HIGH. No equalization occurs in this mode. (Internal pull-down). 8 SQ_ADJ Analog Input Squelch Adjust. Adjusts the approximate amount of cable equalized before CD goes low. See Section 3.3 and Section 3.4. (Internal pull-down). 9, 12 VEE_D Analog Power Most negative power supply for the digital circuitry and output buffer. Connect to GND. 10, 11 SDO, SDO Analog Output Equalized serial digital differential output. |
