Description
The MT9160 5V Multi-featured Codec incorporates a
built-in Filter/Codec, gain control and programmable
sidetone path as well as on-chip anti-alias filters,
reference voltage and bias source. The device
supports both A-Law and µ-Law requirements.
Complete telephony interfaces are provided for
connection to handset transducers. Internal register
access is provided through a serial microport
compatible with various industry standard
micro-controllers. The device also supports
controllerless operation utilizing the default register
conditions.
The MT9160 is fabricated in Mitel's ISO²-CMOS
technology ensuring low power consumption and
high reliability.
