Production Data
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
As per JEDEC specifications A112-A and A113-B, this product requires specific storage conditions prior to surface mount
assembly. It has been classified as having a Moisture Sensitivity Level of 2 and as such will be supplied in vacuum-sealed
moisture barrier bags.

RLC/
GND denotes the voltage of any ground pin.
AGND and DGND pins are intended to be operated at the same potential. Differential voltages between these pins
will degrade performance.
AVDD and DVDD1 pins are intended to be operated at the same potential. Differential voltages between these pins
will degrade performance.
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.

DESCRIPTION
Serial Interface: Enable pulse, active high.
Latched on NRESET rising edge: If Low then device control is via serial interface,
if High then device control is via parallel interface.
Serial Interface: Serial input
data signal.
Serial Interface: Serial clock signal.
Selects whether Reset Level Clamp is
applied (active high). If RLC is required on
every pixel then this pin can be tied high.
Video sample synchronisation pulse.
Master clock. This clock is applied at N times the input pixel rate (N = 8, 6, 3 or 2
depending on the input sampling mode).
Digital ground (0V).
Hi-Z digital 12-bit bi-directional bus, see description for pins OP[2] to OP[11]/SDO.
Digital supply (3.3/5V) for all digital pins.

Parallel Interface: Strobe, active low.
Parallel Interface: High = data,
Low = address.
Parallel Interface:
High = OP[11:4] is output bus,
Low = OP[11:4] is input bus (Hi-Z)
