DS90C383 TSSOP Package Pin Description — FPD Link Transmitter
Pin Name I/O No. Description
TxIN I 28 TTL level input. This includes: 8 Red, 8 Green, 8 Blue, and 4 control lines—FPLINE,
FPFRAME and DRDY (also referred to as HSYNC, VSYNC, Data Enable).
TxOUT+ O 4 Positive LVDS differentiaI data output.
TxOUT− O 4 Negative LVDS differential data output.
FPSHIFT IN I 1 TTL Ievel clock input. The falling edge acts as data strobe. Pin name TxCLK IN.
R_FB I 1 Programmable strobe select.
RTxCLK OUT+ O 1 Positive LVDS differential clock output.
TxCLK OUT− O 1 Negative LVDS differential clock output.
PWR DOWN
I 1 TTL level input. When asserted (low input) TRI-STATES the outputs, ensuring low current at
power down.
