DESCRIPTION
1
Crystal frequency select input. This pin is used to select the master crystal frequency as
follows: FSEL = HIGH = 256f_s; FSEL = LOW = 512f_s; if unconnected the pin will default
HIGH.
2
test input 1; this pin should be left open-circuit
3
test input 2; this pin should be left open-circuit
4
supply ground for the digital section
5
supply voltage for the digital section (+5 V)
6
crystal oscillator input
7
crystal oscillator output
8
system clock output
9
output clock at a frequency half the system clock frequency
10 serial interface clock input
11 serial interface clock output
12 serial interface data output
13 serial interface word select input
14 serial interface word select output
15 input for selecting between the internally generated 1-bit code (DSEL = HIGH) or an
externally generated 1-bit code (DSEL = LOW); if unconnected this pin defaults HIGH
16 1-bit code clock output
17 1-bit code input/output (right channel)
18 1-bit code input/output (left channel)
19 supply ground for the analog timing section
20 supply voltage for the analog timing section (+5 V)
21 voltage reference generator for the right channel analog section
22 output of right channel buffer operational amplifier ‘B’
23 positive input to right channel Sigma-Delta modulator
24 negative input to right channel Sigma-Delta modulator
25 output of right channel buffer operational amplifier ‘A’
26 input of right channel buffer operational amplifier ‘A’
27 negative voltage reference level input for the DACs
28 current reference output
29 positive voltage reference level input for the DACs
30 input of left channel buffer operational amplifier ‘A’
31 output of left channel buffer operational amplifier ‘A’
32 negative input to left channel Sigma-Delta modulator
33 positive input to left channel Sigma-Delta modulator
34 output of left channel buffer operational amplifier ‘B’
35 voltage reference generator for the left channel analog section
36 supply voltage for the analog section (+5 V)
37 supply ground for the analog section
