NXP Semiconductors Preliminary specification

Stereo audio codec with SPDIF interface UDA1355H

5 Data path:

• Input ADC to outputs I

2

S or SPDIF

• Input I

2

S to output DAC.

Features:

• Possibility to process input ADC via

I

2

S-bus using an external DSP and

then to output DAC

• Crystal oscillator generates the clocks

• I

2

S input and output with BCK and WS

are master

• Microcontroller mode: see Section 8.4.

6 Data path:

• Input ADC to output I

2

S

• Input I

2

S to outputs DAC or SPDIF

(level II not guaranteed: depends on

I

2

S-bus clock).

Features:

• Possibility to process input ADC via

I

2

S-bus using an external DSP and

then to outputs DAC or SPDIF

• Crystal oscillator generates the clocks

for input ADC and output I

2

S

• WSI is slave

• WSO is master

• Microcontroller mode: see Section 8.4.
