The MT9196 Integrated Digital Phone Circuit (IDPC) is
designed for use in digital phone products. The device
incorporates a built-in Filter/Codec, digital gain pads,
DTMF generator and tone ringer. Complete telephony
interfaces are provided for connecting to handset and
speakerphone transducers. Internal register access is
provided through a serial microport compatible with
various industry standard micro-controllers.
The device is fabricated in Zarlink's ISO
2
-CMOS
technology ensuring low power consumption and high
reliability.
