TFP401A incorporates HSYNC jitter immunity
Several DVI transmitters available in the market introduce jitter on the transmitted HSYNC and VSYNC signals
during the TMDS encryption process. The HSYNC signal can shift by one pixel position (one clock) from nominal
in either direction, resulting in up to two cycles of HSYNC shift. This jitter carries through to the DVI receiver,
and if the position of HSYNC shifts continuously, the receiver can lose track of the input timing and pixel noise
will occur on the display. For this reason, a DVI compliant receiver with HSYNC jitter immunity should be used
in all displays that could be connected to host PCs with transmitters that have this HSYNC jitter problem.
The TFP401A integrates HSYNC regeneration circuitry that provides a seamless interface to these
noncompliant transmitters. The position of the data enable (DE) signal is always fixed in relation to data,
irrespective of the location of HSYNC. The TFP401A receiver uses the DE and clock signals recreate stable
vertical and horizontal sync signals. The circuit filters the HSYNC output of the receiver, and HSYNC is shifted
to the nearest eighth bit boundary, producing a stable output with respect to data, as shown in Figure 16. This
will ensure accurate data synchronization at the input of the display timing controller.
