DESCRIPTION

21

AVDD

Supply

Analogue supply (5V). This must be operated at the same potential as DVDD1.

22

AGND1

Supply

Analogue ground (0V).

23

VRB

Analogue output

Lower reference voltage.

This pin must be connected to AGND via a decoupling capacitor.

24

VRT

Analogue output

Upper reference voltage.

This pin must be connected to AGND via a decoupling capacitor.

25

VRX

Analogue output

Input return bias voltage.

This pin must be connected to AGND via a decoupling capacitor.

26

VRLC/VBIAS

Analogue I/O

Selectable analogue output voltage for RLC or single-ended bias reference.

This pin would typically be connected to AGND via a decoupling capacitor.

VRLC can be externally driven if programmed Hi-Z.

27

BINP

Analogue input

Blue channel input video.

28

GINP

Analogue input

Green channel input video.

ABSOLUTE MAXIMUM RATINGS

Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at

or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical

Characteristics at the test conditions specified.

ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible

to damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage

of this device.

As per JEDEC specifications A112-A and A113-B, this product requires specific storage conditions prior to surface mount

assembly. It is anticipated as having a Moisture Sensitivity Level of 2 and as such will be supplied in vacuum-sealed moisture

barrier bags.

Notes:

1.

GND denotes the voltage of any ground pin.

2.

AGND1, AGND2 and DGND pins are intended to be operated at the same potential. Differential voltages

between these pins will degrade performance.
