JAJSJG6A december 2021 – june 2023 TDP0604
PRODUCTION DATA
The post-channel, as shown in Figure 9-1, 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 TDP0604 transmitter voltage swing. This is done by configuring the TXSWG pin to the appropriate value as provided in Table 8-12.
The post-channel is greater than 2 inches, then transmitter pre-emphasis may need to be employed. This is done by configuring the TDP0604 TXPRE pin to the appropriate setting as provided in Table 8-11. Adjusting the TDP0604 transmitter voltage swing may also be necessary.
