ADV7344BSTZ Pin Function
Pin No. Mnemonic
Input/
Output
Description
13, 12,
9 to 2 Y9 to Y0 I 10-Bit Pixel Port (Y9 to Y0). Y0 is the LSB. Refer to Table 31 for input modes.
29 to 25,
18 to 14 C9 to C0 I 10-Bit Pixel Port (C9 to C0). C0 is the LSB. Refer to Table 31 for input modes.
62 to 58,
55 to 51 S9 to S0 I 10-Bit Pixel Port (S9 to S0). S0 is the LSB. Refer to Table 31 for input modes.
30 CLKIN_A I Pixel Clock Input for HD only (74.25 MHz), ED
1
only (27 MHz or 54 MHz) or SD only (27 MHz).
63 CLKIN_B I Pixel Clock Input for Dual Modes Only. Requires a 27 MHz reference clock for ED operation or a
74.25 MHz reference clock for HD operation.
50 S_HSYNC I/O SD Horizontal Synchronization Signal. This pin can also be configured to output an SD, ED, or HD
horizontal synchronization signal. See the External Horizontal and Vertical Synchronization
Control section.
49
S_VSYNC
I/O
SD Vertical Synchronization Signal. This pin can also be configured to output an SD, ED, or HD vertical
synchronization signal. See the External Horizontal and Vertical Synchronization Control section.
22 P_HSYNC I ED/HD Horizontal Synchronization Signal. See the External Horizontal and Vertical
Synchronization Control section.
23 P_VSYNC I ED/HD Vertical Synchronization Signal. See the External Horizontal and Vertical Synchronization
Control section.
24 P_BLANK I ED/HD Blanking Signal. See the External Horizontal and Vertical Synchronization Control section.
48 SFL/MISO I/O Multifunctional Pin: Subcarrier Frequency Lock (SFL) Input/SPI Data Output. The SFL input is
used to drive the color subcarrier DDS system, timing reset, or subcarrier reset.
47 R
SET1
I This pin is used to control the amplitudes of the DAC 1, DAC 2, and DAC 3 outputs. For full-drive
operation (for example, into a 37.5 Ω load), a 510 Ω resistor must be connected from R
SET1
to
AGND. For low drive operation (for example, into a 300 Ω load), a 4.12 kΩ resistor must be
connected from R
SET1
to AGND.
36 R
SET2
I This pin is used to control the amplitudes of the DAC 4, DAC 5, and DAC 6 outputs. A 4.12 kΩ
resistor must be connected from R
SET2
to AGND.
45, 35 COMP1,
COMP2 O Compensation Pins. Connect a 2.2 nF capacitor from both COMP pins to V
AA
.
Pin No. Mnemonic

can be connected to other 1.8 V
supplies through a ferrite bead or suitable filtering.
1 V
DD_IO
P Input/Output Digital Power Supply (3.3 V).
34 PV
DD
P PLL Power Supply (1.8 V). For dual-supply configurations, PV
DD
can be connected to other 1.8 V
supplies through a ferrite bead or suitable filtering.
33 EXT_LF1 I External Loop Filter for On-Chip PLL 1.
31 EXT_LF2 I External Loop Filter for On-Chip PLL 2.
32 PGND G PLL Ground Pin.
40 AGND G Analog Ground Pin.
11, 57 DGND G Digital Ground Pin.
64 GND_IO G Input/Output Supply Ground Pin.
1
ED = enhanced definition = 525p and 625p.
2 LSB = least significant bit. In the ADV7344, setting the LSB to 0 sets the I 2 C address to 0xD4. Setting it to 1 sets the I 2 C address to 0xD6.
