Pin Function
PDR-04
Pin No. Pin Name I/O Function
1 CKS 1
Clock selection At normal speed ; L : XTI= 256fs, H : XTI= 384fs
At double speed ; L: XTI= 128fs , H : XTI= 192fs
2 DVDD - Digital power supply
3 DVSS - Digital ground
4 XTO 0 Crystal resonator output
5 XTI 1 Clock input
6 PD 1
Power down
When this pin is set to L, reset the filter and modulator, and it becomes power down state.
7 BICK 1 Serial bit clock 64fs is recommended.
8 SDATA 1 Serial data Input 2's complement, MSB first
9 LRCK 1 UR clock
10 SMUTE 1 Soft mute H: start the soft mute L: release
11 DFS 1 Double speed sampling mode L: Normal speed H: Double speed
12 DEMO 1 Deemphasis mode
13 DEMI 1
It correspond to tri-frequency
14 DIPO 1
Input format
15 DIPI 1
16 BVDD - Power supply
17 AOUTR 0 R ch analog output
18 AOUTL 0 L ch analog output
19 VCOM 0 Common voltage pin, AVDD/2
20 AVDD - Analog power supply
21 AVSS Analog ground
22 VREP 1
Reference voltage input
The voltage difference between this pin and AVSS pin decide to full scale of D/A output.
23 DZP 0
Zero Input detection pin When the data is input to SDATA pin which is continuosly zero for 8192
times on both channels, this pin becomes "H".
24 TTL I I/F level selection T": CMOS level (DVDD= 2.7V to 5.5V) "H": TTL level (DVDD= 4.5V to 5.5V)
