I/O

DESCRIPTION

OGND

19,28,45,

58,76

GND

Output driver ground – Ground reference and current return for digital output drivers

OCK_INV

100

DI

ODCK Polarity – Selects ODCK edge on which pixel data (QE[23:0] and QO[23:0]) and control signals

(HSYNC, VSYNC, DE, CTL1-3 ) are latched

Normal Mode:

High : Latches output data on rising ODCK edge

Low : Latches output data on falling ODCK edge

PD

2

DI

Power down – An active low signal that controls the TFP201/201A power-down state. During power down all

output buffers are switched to a high impedance state. All analog circuits are powered down and all inputs are

disabled, except for PD.

If PD is left unconnected an internal pullup will default the TFP201/201A to normal operation.

High : Normal operation

Low: Power down

PDO

9

DI

Output drive power down – An active low signal that controls the power-down state of the output drivers.

During output drive power down, the output drivers (except SCDT and CTL1) are driven to a high impedance

state. When PDO is left unconnected, an internal pullup defaults the TFP201/201A to normal operation.

High : Normal operation/output drivers on

Low: Output drive power down.

PGND

98

GND

PLL GND – Ground reference and current return for internal PLL

PIXS

4

DI

Pixel select – Selects between one or two pixels per clock output modes. During the 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

Low: 1-pixel/clock

QE[0:7]

10-17

DO

Even blue pixel output – Output for even and odd blue pixels when in 1-pixel/clock mode. Output for even only

blue pixel when in 2-pixel per clock mode. Output data is synchronized to the output data clock, ODCK.

LSB: QE0/pin 10

MSB: QE7/pin 17

QE[8:15]

20-27

DO

Even green pixel output – Output for even and odd green pixels when in 1-pixel/clock mode. Output for even

only green pixel when in 2-pixel/clock mode. Output data is synchronized to the output data clock, ODCK.

LSB: QE8/pin 20

MSB: QE15/pin 27

QE[16:23]

30-37

DO

Even red pixel output – Output for even and odd red pixels when in 1-pixel/clock mode. Output for even only

red pixel when in 2-pixel/clock mode. Output data is synchronized to the output data clock, ODCK.

LSB: QE16/pin 30

MSB: QE23/pin 37

QO[0:7]

49-56

DO

Odd blue pixel output – Output for odd only blue pixel 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/pin 49

MSB: QO7/pin 56

QO[8:15]

59-66

DO

Odd green pixel output – Output for odd only green pixel 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/pin 59

MSB: QO15/pin 66

QO[16:23]

69-75,77

DO

Odd red pixel output – Output for odd only red pixel 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/pin 69

MSB: QO23/pin 77
