Description
Serial Digital Video Channel B Red: SDVOB_RED[±]
is a differential data pair that provides red pixel data for
the SDVOB channel during Active periods. During
blanking periods it may provide additional such as sync
information, auxiliary configuration data, etc. This data
pair must be sampled with respect to the

Serial Digital Video Channel B Green:
SDVOB_GREEN[±] is a differential data pair that
provides green pixel data for the SDVOB channel during
Active periods. During blanking periods it may provide
additional such as sync information, auxiliary
configuration data, etc. This data pair must be sampled
with respect to the SDVOB_CLK[±] signal pair.

Serial Digital Video Channel B Blue:
SDVOB_BLUE[±] is a differential data pair that provides
blue pixel data for the SDVOB channel during Active
periods. During blanking periods it may provide

configuration data, etc. This data pair must be sampled
with respect to the SDVOB_CLK[±] signal pair.

Serial Digital Video Channel B Clock: This
differential clock signal pair is generated by the Intel®
SCH internal PLL and runs between 100 MHz and

If TV-out mode is used, the SDVO_TVCLKIN[±] clock
input is used as the frequency reference for the PLL.
The SDVOB_CLK[±] output pair is then driven back to
the SDVO device.
Serial Digital Video Input Interrupt: Differential
input pair that may be used as an interrupt notification
from the SDVO device to the Intel® SCH. This signal
pair can be used to monitor hot plug attach/detach
notifications for a monitor driven by an SDVO device.
