S-301
ADV7310 (IC302, 501: 1U-3692)
1VDD_IO P Digital power supply.
2~9, 12, 13 Y9-0 I 10-Bit Progressive scan/ HDTV input port for Y data.
10, 56 VDD P Digital power supply.
11, 57 DGND G Digital Ground
14~18, 26~30 C9-0 I 10-Bit Progressive scan/ HDTV input port for CrCb color data in 4:2:2 input mode.
When this input pin is brought low, the ADV7300 interfaces over the SPI port and uses this
19 SPI/I2C I input as part of the 4 wire SPI interface. When this input pin is tied high [VDD_IO], the ADV7300
interfaces over the I2C port.
20 ALSB_SO I/O Multifunctional pin.
21 SDA_CLKSP I/O Multifunctional pin.
22 SCLK_SI I Multifunctional input.
23 P_HSYNC I
Video Horizontal Sync Control Signal for HD sync in simultaneous SD/HD mode
and HD only mode.
24 P_VSYNC I
Video Vertical Sync Control Signal for HD sync in simultaneous SD/HD mode
and HD only mode.
25 P_BLANK I Video Blanking Control Signal for HD sync in simultaneous SD/HD mode and HD only mode.
31 RTC_SCR_TR I Multifunctional input.
32 CLKIN_A I Pixel Clock Input for HD only or SD only modes.
33 RESET I
This input resets the on-chip timing generator and sets the ADV7300 into Default Register
setting. Reset is an active low signal.
34 EXT_LF I External Loop filter for the internal PLL.
35, 47 R
SET1,2 I
A1520 Ohms resistor must be connected from this pin to AGND and is used to control the
amplitudes of the DAC outputs.
36,45 COMP O Compensation Pin for DACs.
37 DAC F O
In SD only mode: Chroma/RED/V analog output.
In HD only mode and simultaneus HD/SD: Pb/ BLUE (HD) analog output.
38 DAC E O
In SD only mode: Luma/BLUE/U analog output.
In HD only mode and simultaneus HD/SD: Pr/ RED (HD) analog output.
39 DAC D O
In SD only mode: CVBS/GREEN/Y analog output.
In HD only mode and simultaneus HD/SD: Y/ GREEN (HD) analog output.
40 AGND G Analog Ground
41 VAA P Analog power supply.
42 DAC C O Chroma/ RED/ V SD analog output.
43 DAC B O Luma/ BLUE/ U SD analog output.
44 DAC A O CVBS/ GREEN/ Y SD analog output.
46 VREF I/O Optional External Voltage Reference Input for DACs or Voltage Reference Output (1.235V).
48 S_BLANK I/O Video Blanking Control Signal for SD.
49 S_VSYNC I/O Video Vertical Sync Control Signal for SD.
50 S_HSYNC I/O Video Horizontal Control Signal for SD.
51~55, 58~62 S9-S0 I
10-Bit Standard Definition input port. Or Progressive Scan/ HDTV input port for
Cr [Red/V] color data in 4:4:4 input mode.
63 CLKIN_B I Pixel Clock Input.
64 GND_IO G Digital Ground
