Digital Interface
3-2
Digital Interface
3.1
Digital Interface
The digital interface consists of six signals that are accessible through J2:
Serial clock (SCLK)
Data in (DIN)
Data out (DOUT)
Frame synchronization (FS)
Chip-select ADC (/CSAD)
Chip-select DAC (/CSDA)
The pin assignments of J2 (see Table 3–1) are compatible with the WYLE TI
C2xx Development System, featuring a TMS320C203 DSP. J2 can be
connected directly to JP3 on the WYLE board. /CSAD is then connected to IO0
of the TMS320C203 and /CSDA to IO1. The positive power supply must be
hardwired to pin 26, as the WYLE board does not provide a signal on pin 26
of JP3 (not used).
Both converters [TLV1570 and the onboard DAC (TLV5616)] have a
TMS320-compatible serial-interface timing. The active device is determined
by two chip-select signals; /CSAD for the TLV1570 and /CSDA for the
TLV5616. Usually, one chip-select signal always should be high to ensure
proper signal routing. However, no bus conflict occurs if both signals are low
(not recommended).
