Preliminary Company Confidential

UV4/SLAEN

O/I

UV4: Digital output UV bus. UV4 used for 16-bit operation for out-

putting chrominance data.

SLAEN: Slave Enable.

UV3/ECLKO

O/I

UV3: Digital output UV bus. UV3 used for 16-bit operation for out-

putting chrominance data.

ECKLO: Swap clock output - changes pin 17(FODD) to XCLK out.

UV2/QVGA

O/I

UV2: Digital output UV bus. UV2 used for 16-bit operation for out-

putting chrominance data.

QVGA: QVGA format (320x240)

UV1/CC656

O/I

UV1: Digital output UV bus. UV1 used for 16-bit operation for out-

putting chrominance data.

CC656: CCIR 656 mode.

UV0/GAMDIS

O/I

UV0: Digital output UV bus. UV0 used for 16-bit operation for out-

putting chrominance data.

GAMDIS: Disables Chroma Gamma (RGB).

27, 28

XCLK1, XCLK2

XO, XI

XCLK1 and XCLK2 are the input/output of the on-chip video oscilla-

tor. Nominal crystal clock frequency is 27MHz. If an external clock is

used, input to XCLK1, leave XCLK2 unconnected.

PCLK/OUTX2

O/I

PCLK: Pixel clock output. By default, data is updated at the falling

edge of PCLK and is stable at its rising edge. PCLK runs at the pixel

rate in 16-bit bus operations and twice the pixel rate in 8-bit bus

operations

OUTX2: Doubles current output.

Y7/CSO

O/I

Y7: Digital output Y bus. In a 16-bit operation, the luminance data is

clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-

ation, the luminance data and the chrominance data is multiplexed

to this bus.

CSO: ID configuation bit for the SCCB slave ID.

Y6/CS2

O/I

Y6: Digital output Y bus. In a 16-bit operation, the luminance data is

clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-

ation, the luminance data and the chrominance data is multiplexed

to this bus.

CS2: ID configuation bit for the SCCB slave ID.

Y5/SHARP

O/I

Y5: Digital output Y bus. In a 16-bit operation, the luminance data is

clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-

ation, the luminance data and the chrominance data is multiplexed

to this bus.

SHARP: Enable Analog Sharpness.

Y4/CS1

O/I

Y4: Digital output Y bus. In a 16-bit operation, the luminance data is

clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-

ation, the luminance data and the chrominance data is multiplexed

to this bus.

CS1: ID configuation bit for the SCCB slave ID.

Y3/RAW

O/I

Y3: Digital output Y bus. In a 16-bit operation, the luminance data is

clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-

ation, the luminance data and the chrominance data is multiplexed

to this bus.

RAW: Raw Data.

Y2/G2X

O/I

Y2: Digital output Y bus. In a 16-bit operation, the luminance data is

clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-

ation, the luminance data and the chrominance data is multiplexed

to this bus.

G2X: Gain 2X.
