LVDS RECEIVER (Figure 48)
Picture data from the SSB is transmitted to the MSB (Main Scaler Board) via the LVDS (Low
Voltage transmission system) to IC 7537. The LVDS receiver has four data lines and one
clock line.
The IC is switched On or Off by the Scaler IC via the LVDS_PWR_DOWN_n line connected
to Pin 25. When AV1, AV2, or the Front (Side) input is selected, the Scaler IC switches Pin
25 High to switch IC 7537 On. The Signal from the Eagle is output to the Scaler as digital Y
and UV. Vertical and Horizontal Sync is output on Pin 54 and 55. The Clock data signal is
output on Pin 26. The DE_EMG line goes High when the IC is switched On to signal the
Scaler IC that data is present from this IC.
