Description
The MT9160B/61B 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 ITU-T and sign-magnitude
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 MT9160B/61B is fabricated in Mitel's
ISO²-CMOS technology ensuring low power
consumption and high reliability.
