VP5313/VP5513
4
Pin Name Pin No. Description
PD0-7 2-4, 8 Bit Pixel Data inputs clocked by PXCK. PD0 is the least significant bit. These pins are
internally pulled low.
PXCK 44 27MHz Pixel Clock input. The VP5313/VP5513 internally divides PXCK by two to provide the
pixel clock.
SA 18 Slave address select.
SCL 23 Standard I
2
C bus serial clock input.
SDA 24 Standard I2C bus serial data input/output.
FC0-2 12-14 Field Counter output in master sync mode.
REFSQ 9 Reference square wave input used only during Genlock mode.
SCSYNC 8 Subcarrier sync input, (synchronises phase quadrant in 4xfsc genlock mode), see fig 6.
PALID 7 PAL IDENT input, controls swinging colour burst phase in PAL genlock mode.
COMPSYNC 6 Composite sync pulse output. This is an active low output signal.
CLAMP 5 The CLAMP output signal is synchronised to COMPSYNC output and indicates the position of
the BURST pulse, (lines 10-263 and 273-525 for NTSC; lines 6-310 and 319-623 for PAL-
B,D,G,I,N(Argentina)).
TTXREQ 17 Teletext Data Request output, requests next line of teletext data.
TTXDATA 19 Teletext Data input.
HSYNC 15 Horizontal Sync, output in master mode, input in slave mode
VSYNC 16 Vertical Sync, output in master mode, input in slave mode
RESET 22 Master reset. This is an asynchronous, active low, input signal and must be asserted for a
minimum 200ns in order to reset the VP5313/VP5513.
VREF 33 Voltage reference output. This output is nominally 1·0V and should be decoupled with a
100nF capacitor to GND.
RREF 34 DAC full scale current control. A resistor connected between this pin and GND sets the
magnitude of the video output current. An internal loop amplifier controls a reference current
flowing through this resistor so that the voltage across it is equal to the Vref voltage. This
reference current has a weighting equal to 20.8 LSB’s.
DACCOMP 25 DAC compensation. A 100nF ceramic capacitor must be connected to AVDD.
CVBS1 32 Composite video output. These are high impedance current source outputs. A DC path to
GND must exist from each of these pins.
BLUE/CVBS2 31 Blue or composite DAC output. Output type as CVBS1.
GREEN/Y 27 Green or luminance DAC output. Output type as CVBS1.
RED/C 26 Red or chrominance DAC output. Output type as CVBS1.
VDD 1, 11, 20 Positive supply input. All VDD pins must be connected.
AVDD 37,28,30 Analog positive supply input. All AVDD pins must be connected.
GND 10,21,43 Negative supply input. All GND pins must be connected.
AGND 36,29,35 Analog negative supply input. All AGND pins must be connected.
