GS1559 Data Sheet
4.7.4 HVF Timing Signal Generation
The GS1559 extracts critical timing parameters from either the received TRS
signals (FW_EN/DIS = LOW), or from the internal flywheel-timing generator
(FW_EN/DIS = HIGH).
Horizontal blanking period (H), vertical blanking period (V), and even / odd field (F)
timing are all extracted and presented to the application layer via the H:V:F status
output pins.
The H signal timing is configurable via the H_CONFIG bit of the internal
IOPROC_DISABLE register as either active line based blanking, or TRS based
blanking, (see
Error Correction and Insertion on page
56).
Active line based blanking is enabled when the H_CONFIG bit is set LOW. In this
mode, the H output is HIGH for the entire horizontal blanking period, including the
EAV and SAV TRS words. This is the default H timing used by the device.
When H_CONFIG is set HIGH, TRS based blanking is enabled. In this case, the H
output will be HIGH for the entire horizontal blanking period as indicated by the H
bit in the received TRS ID words.
The timing of these signals is shown in
Figure
4-3.
