9.5.4 I2C interconnect
Figure 9-44 I2C interconnect
The OTC communicates with the set via three I2C busses.
SDA-F, Fast bus communicates with the PICNIC, HIP, and
MSP (Audio Processor). The SN-DA line from the PICNIC
communicates with the FALCONIC and EAGLE. The SDA-S
Slow bus communicates with the Tuner, AV Switch, and
ComPair connector on the SSM. It also communicates with the
PIP-DW board.
The TXD and RXD lines communicate with the microprocessor
on the ACS module. The microprocessor on the ACS
communicates with the GDE NVM, Convergence Processor,
and the HOP panel.
9.5.5 On-Screen Display
Figure 9-45 On-Screen Display
Signal for the OSD (On-Screen Display) comes from three
different sources. IC 7001, which is located on the SSB (Small
Signal Board), generates all of the customer menus except for
Convergence.
In the SAM (Service Alignment Mode), the menus are
generated by 7001, except those in the GDE SAM. The GDE
SAM menus are generated by IC 7100 on the ACS module.
The Convergence Alignment menus are generated by 7100,
while the Convergence Alignment grid is generated by IC 7002.
The OSD signals from 7001 on the SSB are fed to the SSM
(Small Signal Module) via connector 1002 and 1043. The OSD
signals from the Convergence Processor, 7002, are buffered
by 7014 through 7017 before being mixed with the signals from
the ACS microprocessor, 7100. They are fed to the SSM via
connector 1000. The signals from the ACS and SSB are mixed
and fed to the HOP panel and HOP IC, 7600, via connector
1610. The HOP IC, 7600, mixes the OSD signal with the video
signal before feeding it to the CRTs.
