3 Serial Communications
DOUT, DIN, SCLK, FS, and FC are the serial communication signals. The digital output data from the ADC
is taken from DOUT. The digital input data for the DAC is applied to DIN. The synchronizing clock for the
serial communication data and the frame sync is taken from SCLK. The frame-sync pulse that encloses the
ADC and DAC data transfer interval is taken from FS. For signal data transmitted from the ADC or to the
DAC, primary serial communication is used. To read or write words that control both the options and the
circuit configurations of the device, secondary communication is used.
The purpose of the primary and secondary communications is to allow conversion data and control data to
be transferred across the same serial port. A primary transfer is always dedicated to conversion data. A
secondary transfer is used to set up and/or read the register values. A primary transfer occurs for every
conversion period. A secondary transfer occurs only when requested. Secondary serial communication can
be requested either by hardware (FC terminal) or by software (D0 of primary data input to DIN).
3.1
Primary serial communication is used both to transmit and receive conversion signal data. The DAC word
length depends on the state of bit D0 in control 1 register. After power up or reset, the device defaults to the
15-bit mode. When the DAC word length is 15 bits, the last bit of the primary 16-bit serial communication
word is a control bit used to request secondary serial communication. In the 16-bit mode, all 16 bits of the
primary communication word are used as data for the DAC and the hardware terminal FC must be used to
request secondary communication.
Primary Serial Communication
Figure 3–1 shows the timing relationship for SCLK, FS, DOUT and DIN in a primary communication. The
timing sequence for this operation is as follows:
1.
FS is brought low by the TLC320AD50C, TLC320AD50I, or TLC320AD52C.
2.
A 16-bit word is transmitted from the ADC (DOUT) and a 16-bit word is received from the DAC
(DIN).
3.
FS is brought high by the TLC320AD50C, TLC320AD50I, or TLC320AD52C, signaling the end
of the data transfer.
