Description
The MT9160B 5V Multi-featured Codec is a
replacement for the MT9160.
The major difference is the improvement in idle
channel noise performance over and above that of
the MT9160.
Typical Performance
Transmit
10 dBrnC0 µ-law
-70 dBm0p A-Law
Receive
9 dBrnC0 µ-law
-81 dBm0p A-Law
Another difference is that V_Bias - V_Ref = 1.9 Volts.
For other performance features, please refer to the
MT9160 data sheet.
