Pin Type
UV2: Digital output UV bus. UV2 used for 16-bit operation for outputting
chrominance data.
QVGA: QVGA format (320x240)
UV1: Digital output UV bus. UV1 used for 16-bit operation for outputting
chrominance data.
CC656: CCIR 656 mode.
UV0: Digital output UV bus. UV0 used for 16-bit operation for outputting
chrominance data.
GAMDIS: Disables Chroma Gamma (RGB).
XCLK1 and XCLK2 are the input/output of the on-chip video oscillator. Nominal
crystal clock frequency is 27MHz. If an external clock is used, input to XCLK1,
leave XCLK2 unconnected.
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: 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 operation, the luminance
data and the chrominance data is multiplexed to this bus.
CSO: ID configuation bit for the SCCB slave ID.
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 operation, the luminance
data and the chrominance data is multiplexed to this bus.
CS2: ID configuation bit for the SCCB slave ID.
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 operation, the luminance
data and the chrominance data is multiplexed to this bus.
SHARP: Enable Analog Sharpness.
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 operation, the luminance
data and the chrominance data is multiplexed to this bus.
CS1: ID configuration bit for the SCCB slave ID.
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 operation, the luminance
data and the chrominance data is multiplexed to this bus.
RAW: Raw Data.
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 operation, the luminance
data and the chrominance data is multiplexed to this bus.
G2X: Gain 2X.
Y1: 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 operation, the luminance
data and the chrominance data is multiplexed to this bus.
PROG: Progressive Scan Mode.
Y0: 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 operation, the luminance
data and the chrominance data is multiplexed to this bus.
CBAR: Color Bar Test Pattern.
CHSYNC: Digital output for either composite sync or horizontal sync signal.
BW: Enables Black & White.
SCCB Serial clock input with schmitt trigger.
SCCB Serial data, input with schmitt trigger.
