external video system.
VDAC_C/VDAC_Cn
Video DAC Composite Video
Output/Input
The composite video output signal to the external video
system.
VREFIN
VDAC Bias Generator Voltage Reference
Input
Voltage reference for VDAC bias generator. Normally
connect VREFOUT to VREFIN externally.
VREFOUT
VDAC Bandgap Voltage Reference
Output
Output 1.23 V nominal voltage from internal bandgap.
Connect a 100 nF decoupling capacitor between
VREFOUT and AVSS1.
IREF
VDAC Bias Generator Current Reference
Output
Bias Generator sinks 135 uA into an external resistor of
9.1 K
connected between IREF and AVSS1. Uses
PLLDDRVOLS I/O cell.
FR_32PD
3:2 Pulldown Indicator
Output
This signal is asserted when the video interface is
performing 3:2 pulldown to display a 24-frame bitstream
at 30 frames per second.
