WebHowever, the QPLL can support lower TMDS clock frequencies than the CPLL. The CPLL's VCO must run in the range of 1.6 GH z to 3.3 GHz. The VCO frequency is dependent upon the TMDS clock frequency. The CPLL can apply a limited set of multipliers to the TMDS clock frequency. The GT driver measures the TMDS clock frequency and attempts to find a valid WebIt receives the serial data and clock time stamp through the fourth channel and then decodes the data and outs the data in parallel to the display controller. How TMDS Work: It uses four channels, namely Red, Green, Blue, and Clock, similar to the traditional RGBHV. It has two-stage processes.
