Description
Power supply connection for the serial digital cable driver. Connect to
+1.8V DC analog.
Serial digital loop-through output signal operating at 1.485Gb/s,
1.485/1.001Gb/s, or 270Mb/s.
The slew rate of these outputs is automatically controlled to meet SMPTE
292M and 259M requirements according to the setting of the SD/HD pin.
Ground connection for the serial digital cable driver. Connect to analog
GND.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to select JTAG Test Mode or Host Interface Mode.
When set HIGH, CS_TMS, SDOUT_TDO, SDI_TDI and SCLK_TCK are
configured for JTAG boundary scan testing.
When set LOW, CS_TMS, SDOUT_TDO, SDI_TDI and SCLK_TCK are
configured as GSPI pins for normal host interface operation.
STATUS SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to indicate the ODD / EVEN field of the video signal.
The F signal will be HIGH for the entire period of field 2 as indicated by the
F bit in the received TRS signals.
The F signal will be LOW for all lines in field 1 and for all lines in
progressive scan systems.
