Line-locked data output clock
External clock reference input. It can be connected to an external oscillator with a 1.8-V
XTAL1
74
I
compatible clock signal or a 14.31818-MHz crystal oscillator.
External clock reference output. Not connected if XTAL1 is driven by an external single-ended
XTAL2

oscillator.
Digital Video
57, 58, 59,
Digital video output of CbCr, C[9] is MSB and C[0] is LSB. C_0 and C_[9-2] can be used as
60, 63, 64,
programmable general purpose I/O. C_1 (pin 69) requires an external pulldown resistor and
C_[9:0]
I/O
65, 66, 69,
should not be used for general purpose I/0.
70
For the 8-bit mode, the two LSBs are ignored. Unused outputs can be left unconnected.
43, 44, 45,
46, 47, 50,
Digital video output of Y/YCbCr, Y[9] is MSB and Y[0] is LSB.
Y[9:0]
O
51, 52, 53,
For the 8-bit mode, the two LSBs are ignored. Unused outputs can be left unconnected.

Miscellaneous Signals
GPIO
35
I/O
Programmable general-purpose I/O
Genlock control output (GLCO) uses real time control (RTC) format.
GLCO/I2CA
37
I/O
During reset, this terminal is an input used to program the I2C address LSB.
