VDD

±5 V ± 5% power supply.

1, 6, 7, 9, 26, 30, 35,

40, 43, 60, 64

GND

Ground.

SCAN_EN

Set Low.

SI9..0

Input Data Port: Input data port with internal pull-downs. Input data is assumed to be a

multiplexed stream of CBYCR [Y] CB..., where [Y] denotes an isolated Luminance sample.

SI9 is the Most Significant Bit and SI0 is the Least Significant Bit.

4OE

Output Enable: Active low input with internal pull-up. When OE is high, the output data ports

are in high impedance state.

59-53, 51-49

SOA9..0

Output Data Port A: Depending on device configuration, SOA9..0 may output over-sampled

Y or G video. SOA9 is the Most Significant Bit and SOA0 is the Least Significant Bit.

48-45, 42, 41, 39-37,

SOB9..0

Output Data Port B: Depending on device configuration, SOB9..0 may output over-sampled

CB or B video. SOB9 is the Most Significant Bit and SOB0 is the Least Significant Bit.

33-31, 29, 28, 25-21

SOC9..0

Output Data Port C: Depending on device configuration, SOC9..0 may output over-sampled

CR or R video. SOC9 is the Most Significant Bit and SOC0 is the Least Significant Bit.

CLK

System Clock: All timing information relative to rising edge of clock.

SYNC

Synchronization: Control signal input with internal pull-up. This input is used to synchronize

the incoming data by holding SYNC high on clock period N and low on clock period N+1

when the first CB sample is presented to the SI9..0 inputs. SYNC may be held low until re-

synchronization is desired or may be toggled at every occurrence of a CB sample.

SELECT_MATRIX

Select Color Space Conversion: Control signal input with internal pull-down.

SELECT_MATRIX is used to enable and disable the internal YCBCR to RGB color space

converter. Color space conversion is enabled while SELECT_MATRIX is high and is

disabled while SELECT_MATRIX is low.

BYPASS

Bypass SIN X/X Correction: Control signal input with internal pull-up. When BYPASS is

high, SIN X/X correction for the three output channels is enabled. While BYPASS is low, SIN

X/X correction is by-passed.

SETUP

Setup: Control signal input with internal pull-down. SETUP is used to enable and disable

setup insertion in the Luminance channel.

CONVERT

Two's Complement Conversion: Control signal input with internal pull-up. While CONVERT

is high, SOB9..0 and SOC9..0 output signed (two’s complement) digital data. While

CONVERT is low, SOB9..0 and SOC9..0 output unsigned (offset binary) data. When

operating in RGB output mode, the CONVERT pin is over-ridden and both SOB9..0 and

SOC9..0 output unsigned digital data. SOA9..0 outputs unsigned digital data in all operating

modes.

RND10/8

Output Rounding: Control signal input with internal pull-up. RND10/8 selects rounding to

10 bit resolution per channel when high and rounding to 8 bit resolution per channel when

low.
