DSP interface
The TLV1544/1548 can also interface with a DSP, from the TMS320 family for example, through a serial port.
The analog-to-digital converter (ADC) serves as a slave device where the DSP supplies FS and the serial I/O
CLK. Transmit and receive operations are concurrent. The falling edge of FS must occur no later than seven
I/O CLK periods after the falling edge of CS.
DSP I/O cycles differ from microprocessor I/O cycles in the following ways:
D When interfaced with a DSP, the output data MSB is available afterFS↓. The remaining output datachanges
on the rising edge of I/O CLK. The input data is sampled on the first four falling edges of I/O CLK after FS
↓
and when INV CLK is high, or the first four rising edges of I/O CLK after FS
↓ and when INV CLK is low. This
operation is inverted when interfaced with a microprocessor.
D A new DSP I/O cycle is started on the rising edge of I/O CLK after the rising edge of FS. The internal state
machine is reset on each falling edge of I/O CLK when FS is high. This operation is opposite when interfaced
with a microprocessor.
D The TLV1544/1548 supports a 16-clock cycle when interfaced with a DSP. The output data is padded with
six trailing zeros when it is operated in DSP mode.
