I/O
DESCRIPTION
PGND
98
PLL ground. Ground reference and current return for internal PLL.
PIXS
4
I
Pixel select. Selects between 1- or 2-pixel/clock output mode. During 2-pixel/clock mode, both even pixels,
QE[23:0], and odd pixels, QO[23:0], are output in tandem on a given clock cycle. During 1-pixel/clock, even
and odd pixels are output sequentially, one at a time, with the even pixel first, on the even pixel bus, QE[23:0].
(The first pixel per line is pixel-0, the even pixel. The second pixel per line is pixel-1, the odd pixel.)
High: 2-pixel/clock mode
Low: 1-pixel/clock mode
PVDD (1, 2)
97, 99
PLL VDD. Power supply for internal PLL. Nominally 3.3 V.
QE[0:7]
1017
O
Even blue pixel output. Output for even and odd blue pixels when in 1-pixel/clock mode. Output for only even
blue pixels when in 2-pixel/clock mode. Output data is synchronized to the output data clock, ODCK.
LSB: QE0 (terminal 10)
MSB: QE7 (terminal 17)
QE[8:15]
2027
O
Even green pixel output. Output for even and odd green pixels when in 1-pixel/clock mode. Output for only
even green pixels when in 2-pixel/clock mode. Output data is synchronized to the output data clock, ODCK.
LSB: QE8 (terminal 20)
MSB: QE15 (terminal 27)
QE[16:23]
3037
O
Even red pixel output. Output for even and odd red pixels when in 1-pixel/clock mode. Output for only even red
pixels when in 2-pixel/clock mode. Output data is synchronized to the output data clock, ODCK.
LSB: QE16 (terminal 30)
MSB: QE23 (terminal 37)
QO[0:7]
4956
O
Odd blue pixel output. Output for only odd blue pixels when in 2-pixel/clock mode. Not used and held low when
in 1-pixel/clock mode. Output data is synchronized to the output data clock, ODCK.
LSB: QO0 (terminal 49)
MSB: QO7 (terminal 56)
QO[8:15]
5966
O
Odd green pixel output. Output for only odd green pixels when in 2-pixel/clock mode. Not used and held low
when in 1-pixel/clock mode. Output data is synchronized to the output data clock, ODCK.
LSB: QO8 (terminal 59)
MSB: QO15 (terminal 66)
QO[16:23]
6975,
77
O
Odd red pixel output. Output for only odd red pixels when in 2-pixel/clock mode. Not used and held low when in
1-pixel/clock mode. Output data is synchronized to the output data clock, ODCK.
LSB: QO16 (terminal 69)
MSB: QO23 (terminal 77)

I/O
These terminals are the I2C interface to the internal HDCP key EEPROM. Each terminal requires a 10-k
pullup resistor connected to VDD.
