3.3.5.2. PMA Configuration Rules for HDMI Mode

Whe you select HDMI fo the PMA cofiguatio ules settig i the GTS PMA/FEC Diect PHY Itel FPGA IP, the TX PLL itege mode efeece clock fequecy paamete fo System PLL clockig mode ca be set to the miimum value of 25 MHz. Due to Dyamic Recofiguatio equiemets of the HDMI potocol, oly the System PLL clockig mode is applicable fo HDMI applicatios. This HDMI selectio also eables you to implemet the dual simplex mode fo the GTS PMA/FEC Diect PHY Itel FPGA IP. Refe to the GTS Tasceive Dual Simplex Itefaces Use Guide fo details o how to implemet the dual simplex mode.

The followig cofiguatios ae suppoted i HDMI mode.
Table 29.  Cofiguatios Suppoted i HDMI Mode
Cofiguatio Data Rate pe Lae (Gbps) Refclk Fequecies (MHz) Numbe of Laes
HDMI 2.0 (Icludig HDMI 1.4b) 0.25 - 6 25 - 340 3 laes
HDMI 2.1 3, 6, 8, 10, 12 100 3 o 4 laes
Note: HDMI is a backwad compatible potocol, theefoe HDMI 1.4b is also suppoted. Fo data ates less tha 1 Gbps, you must use ovesamplig to comply with the miimum data ate of the GTS tasceive. A efeece clock of less tha 100 MHz fo the System PLL is oly applicable i HDMI mode.

You ca implemet the HDMI mode cofiguatio usig the GTS PMA/FEC Diect PHY Itel FPGA IP ad combie it with the GTS HDMI Itel FPGA IP, which povides the uppe laye potocol implemetatio fo the HDMI potocol. Thee ae desig examples that demostate the complete solutio of the HDMI potocol that you ca geeate fom the GTS HDMI Itel FPGA IP. Refe to the GTS HDMI Itel FPGA IP Desig Example Use Guide fo moe details.
