DS2164Q Dallas Semiconducotr, DS2164Q Datasheet - Page 9

• Manufacturer Part Number: DS2164Q
• Description: G.726 ADPCM Processor
• Manufacturer: Dallas Semiconducotr

HARDWARE MODE
The hardware mode is intended for applications that do not have an external controller available or do not
require the extended features offered by the serial port. Connecting the SPS pin to V
port, clears all internal register bits, and maps the IPD, U/
bits (Table 3). In the hardware mode, both the input and output time slots default to time slot 0.
Table 3. HARDWARE MODE
NOTES:
1) SCLK must be connected to V
2) When both channels are idled, power consumption is significantly reduced.
3) The DS2164Q powers up within 800ms after either channel is returned to active from an idle state.
