APPLICATION INFORMATION
DSP serial interface
Utilizing a simple 3-wire serial interface, the TLC5617A can be interfaced to TMS320 compatible serial ports.
The 5617A has an internal state machine that counts 16 clocks after receiving a falling edge of CS and then
disable further clocking in of data until the next falling edge is received on CS. Therefore the CS can be
connected directly to the FS pins of the serial port and only the leading falling edge of the DSP will be used to
start the write process. The TLC5617A is designed to be used with the TMS320Cxx DSP in burst mode serial
port transmit operation.

SPI serial interface
Both the TLC5617 and TLC5617A are compatible with SPI, QSPI, or Microwire serial standards. The hardware
connections are shown in Figure 23 and Figure 24. The TLC5617A has an internal state machine that counts
16 clocks after the falling edge of CS and then internally disables the device. The internal edge is ORed together
with CS so that the rising edge can be provided to CS prior to the occurrence of the internal edge to also disable
the device.
general serial interface
The TLC5617 3-wire interface is compatible with the SPI, QSPI, and Microwire serial standards. The hardware
connections are shown in Figure 23 and Figure 24.
The SPI and Microwire interfaces transfer data in 8-bit bytes, therefore, two write cycles are required to input
data to the DAC. The QSPI interface, which has a variable input data length from 8 to 16 bits, can load the DAC
input register in one write cycle.
