Transmitter
Figure 1. Transmitter Board
- The GT transmitter does not support TMDS Level Signaling and must be used with a cable driver to be compliant with TMDS specifications.
- TMDS Level Shifting can be done using external level shifter ASSPs such
as:
- Texas Instruments SN65DP159
- ON Semiconductor NB7NQ621M (HDMI 2.1)
- Board design simulation must be done to ensure proper operation.
Receiver
Figure 2. Receiver Board
- The GT Receiver does not support TMDS Level Signaling and must be used with a retimer or equalizer to be compliant with the TMDS specification.
- TMDS levels are emulated using external pull-up resistors (located close to the device GTs).
- Use external TMDS Retimer/EQ chip recommended for HDMI 2.0 data rates such
as:
- Texas Instruments TMDS181
- ON Semiconductor NB7NQ621M (HDMI 2.1)
- Board design simulation must be done to ensure proper operation.
