HARDWARE MODE

The hardware mode is intended for preliminary system

prototyping or for applications which do not require the

features of the serial port. Tying SPS to VSS disables

the serial port, clears all internal registers and maps

IPD, µ/A and CP/EX of the X and Y side interfaces to the

port and address inputs. Input and output timeslots for

the X and Y side interfaces are fixed at 0. Such applica-

tions include, but are not limited to: 1) systems in which

timeslot and algorithm are fixed, 2) stand-alone ADPCM

combo applications, 3) “hardware” oriented systems

where no host controller is available.

NAMES AND DESCRIPTION

Channel X coding

0 = Expand

1 = Compress

Channel X data format

0 = A-law

1 = µ-law

Channel Y coding

0 = Expand

1 = Compress

Channel Y data format

0 = A-law

1 = µ-law

Y idle select

0 = Channel active

1 = Channel idle

X idle select

0 = Channel active

1 = Channel idle

NOTES:

1. SCLK, A1 and A4 must be tied to VSS when the hardware mode is selected.

2. When both X and Y sides are idled, the devices enter a stand-by mode which significantly reduces power

consumption.

3. The DS2167 will power-up within 200 ms after the X or Y side is reactivated (SDI and/or CS not equal to 0)

from standby.

4. The DS2168 must be hardware reset when reactivated from standby. Power-up occurs immediately after the

reset.
