JAJSOZ7A August 2022 – April 2024 TMDS1204
PRODUCTION DATA
Figure 8-1 shows the post-channel, which should be 2 inches or less. If ESD devices are used, then it may be necessary to overcome the insertion loss of the ESD device by increasing the TMDS1204 transmitter voltage swing. Table 7-17 lists how this is done by configuring the TXSWG pin to the appropriate value.
If post-channel is greater than 2 inches, then transmitter pre-emphasis may need to be employed. Table 7-15 lists how this is done by configuring the TMDS1204 TXPRE pin to the appropriate setting. Adjusting the TMDS1204 transmitter voltage swing may also be necessary.
