Ground connection for the phase detector. Connect to analog GND.

Charge pump current setting resistor.

Ground pins for the VCO.

Ground pin for the charge pump and PLL.

PARALLEL DATA TIMING

Signal levels are LVCMOS/LVTTL compatible.

TIM_861 = LOW:

The V signal is used to indicate the portion of the video field/frame

that is used for vertical blanking, when DETECT_TRS is set LOW.

The V signal should be set HIGH for the entire vertical blanking

period and should be set LOW for all lines outside of the vertical

blanking interval.

The V signal is ignored when DETECT_TRS = HIGH.

TIM_861 = HIGH:

The VSYNC signal indicates vertical timing. See Section 4.3.1 for

timing details.

The VSYNC signal is ignored when DETECT_TRS = HIGH.

Ground connection for the serial digital cable driver. Connect to

analog GND.

Serial digital output signal operating at 1.485Gb/s, 1.485/1.001Gb/s,

or 270Mb/s.

The slew rate of these outputs is automatically controlled to meet

SMPTE 292M and 259M requirements according to the setting of

the SD/HD pin.

Serial digital output signal from the internal cable driver.

NOTE: The SDO/SDO output signals will be set to high impedance

when RESET = LOW.
