Drive Strength Selection (Clock)
DR_STR_C[1:0] Address 0xF4[3:2]
The DR_STR_C[1:0] bits can be used to select the strength of
the clock signal output driver (LLC pin). For more information,
refer to the
Strength Selection (Data) sections.

Drive Strength Selection (Sync)
DR_STR_S[1:0] Address 0xF4[1:0]
The DR_STR_S[1:0] bits allow the user to select the strength of
the synchronization signals with which HS, VS, and F are
driven. For more information, refer to the
Selection (Clock) and the
sections.

Enable Subcarrier Frequency Lock Pin
EN_SFL_PIN Address 0x04[1]
The EN_SFL_PIN bit enables the output of subcarrier lock
information (also known as GenLock) from the ADV7183B to
an encoder in a decoder-encoder back-to-back arrangement.
When EN_SFL_PIN is 0 (default), the subcarrier frequency lock
output is disabled.
When EN_SFL_PIN is 1, the subcarrier frequency lock infor-
mation is presented on the SFL pin.
Polarity LLC Pin
PCLK Address 0x37[0]
The polarity of the clock that leaves the ADV7183B via the
LLC1 and LLC2 pins can be inverted using the PCLK bit.
Changing the polarity of the LLC clock output can be necessary
to meet the setup-and-hold time expectations of follow-on
chips.
This bit also inverts the polarity of the LLC2 clock.
When PCLK is 0, the LLC output polarity is inverted.
When PCLK is 1 (default), the LLC output polarity is normal
(as per the timing diagrams).
