J4
Feedback connection to crystal. If the reference clock source is a clock oscillator, this pin should be
grounded through a 2.7K pulldown resistor.
XTAL

H4
Crystal/oscillator input. For crystal, the frequency restrictions are: Min = 14MHz Max = 50MHz. For
oscillator, Min = 14 MHz, Max = 24 MHz [3.3V level]

Input YUV data in ITU-R BT656 format with embedded SAV and EAV.
These inputs feature internal pull-downs. Any external pull-ups used on these inputs should not exceed
10k ohms. Larger values run the risk of lowering the input high voltage to a value that would create
large currents in the input pads.
YUV(7:0) incorporate General Purpose Inputs (GPIs) . See Section 4.19.1.

HCLK / SCL
I
P1
Host Protocol input clock. HCLK for 6-wire nibble, SCL for 2-wire mode.
[Input, schmitt trigger (400mV typical hysteresis), 5V-tolerant]
Host Protocol framing signal for 6-wire nibble mode. Also used as SDA (open drain) signal for 2-wire
mode. [Bidirectional, 4mA drive output, Schmitt trigger input (400mV typical hysteresis), 5V-tolerant]
Host Protocol data nibble for 6-wire mode. The upper nibble byte(3:0) is transferred first followed by
lower nibble byte(7:4).
