- 40 -IC SAA5264PS/M3/0104 SDIP52
Pin No. Pin Name Description
37 VSYNC Vertical sync pulse input; Schmitt triggered for a TTL version; the
polarity of this pulse is programmable by register bit TXT1. V POLARITY
38 VSSP Periphery ground
39 VDDC Core supply voltage (+3.3V)
40 OSCGND Crystal oscillator ground
41 XTALIN 12 MHz crystal oscillator input
42 STALOUT 12 MHz crystal oscillator output
43 RESET Reset input; if this pin is HIGH for at least 2 machine cycles (24 oscillator
periods) while the oscillator is running, the device resets; this pin
should be connected to VDDP via a capacitor

INFORMATION OF ICS
IC TPA1517NE DIP20
Pin No. Pin Name Description
1IN1 IN1 is the audio input for channel 1.
2SGND SGND is the input signal ground reference.
3SVRR SVRR is the midrail bypass.
4OUT1 OUT1 is the audio output for channel1.
5PGND PGND is the power ground reference.
6OUT2 OUT2 is the audio output for channel 2.
7 VCC VCC is the supply voltage input.
8M/SB M/SB is the mute/standby mode enable. When held at less than 2 V,
this signal enables the TPA1517 for standby operation. When held
between 3.5V and 8.2V,this signal enables the TPA1517 for mute
operation. When held above 9.3V, the TPA1517 operates normally.
9IN2 IN2 in the audio input for channel 2.
10-20 GND/HS GND/HS are the ground and heatsink connections. All GND/HS
terminals are connected directly to the mount pad for thermal-enhanced
operation.
IC TVP5146PFP S-PQFP-G80 (Clock Signals)
Pin No. Pin Name Description
40 DATACLK Line-locked data output clock.
74 XTAL1 External clock reference input. it may be connected to an external
oscillator with a 1.8V compatible clock signal or a 14.31818-MHz
crystal oscillator.
75 XTAL2 External clock reference output. Not connected if XTAL1 is driven by an
external single-ended oscillator.
