APPLICATION INFORMATION
serial interface (continued)
If there is no need to have more than one device on the serial bus, then CS can be tied low. Figure 16 shows
an example of how to connect the TLV5614 to a TMS320, SPI, or Microwire port using only three pins.

Figure 16. Three-Wire Interface
Notes on SPI and Microwire: Before the controller starts the data transfer, the software has to generate a falling
edge on the I/O pin connected to FS. If the word width is 8 bits (SPI and Microwire), two write operations must
be performed to program the TLV5614. After the write operation(s), the DAC output is updated automatically
on the next positive clock edge following the sixteenth falling clock edge.
serial clock frequency and update rate
The maximum serial clock frequency is given by:
f
SCLKmax +

wH(min) )

wL(min)
+ 20 MHz
The maximum update rate is:
f
UPDATEmax +

+ 1.25 MHz
Note that the maximum update rate is a theoretical value for the serial interface since the settling time of the
TLV5614 has to be considered also.
data format
The 16-bit data word for the TLV5614 consists of two parts:
D Control bits
