Description
Horizontal SYNC Output. Note: HS transition restrictions: 1. 12-bit Low-Frequency
mode: No HS restrictions (raw) 2. 12-bit High-Frequency mode: No HS restrictions
(raw) 3. 10-bit High-Frequency mode: HS restricted to no more than one transition per
10 PCLK cycles.
Vertical SYNC Output. Note: VS transition restrictions: 1. 12-bit Low-Frequency mode:
No VS restrictions (raw) 2. 12-bit High-Frequency mode: No VS restrictions (raw) 3.
10-bit High-Frequency mode: VS restricted to no more than one transition per 10
PCLK cycles.
Pixel Clock Output Pin.
Strobe edge set by RRFB control register.
General-purpose input/output pins can be used to control and respond to various
commands. They may be configured to be the input signals for the corresponding
GPOs on the serializer or they may be configured to be outputs to follow local register
settings.
General purpose input/output pins GPO[3:2] can be configured to be input signals for
GPOs on the Serializer. In addition they can also be configured to be outputs to follow
the local register settings. When the SerDes chipsets are working with an external
oscillator, these pins can be configured only to be outputs to follow the local register
settings.
