Zarlink Semiconductor Inc.
Table 1 - Law Selection
Analog Interfaces
Standard interfaces are provided by the MT9162. These are:
The analog inputs (transmitter), pins AIN+/AIN-. The maximum peak to peak input is 3.667Vpp
μ
law and across
AIN+/AIN- 3.8Vpp A-law.
The analog outputs (receiver), pins AOUT+/AOUT-.This internally compensated fully differential output driver is
capable of driving a load of 20k ohms.
PCM Serial Interface
A serial link is required to transport data between the MT9162 and an external digital transmission device. The
MT9162 utilizes the strobed data interface found on many standard Codec devices. This interface is commonly
referred to as Simple Serial Interface (SSI).
The required mode of operation is selected via the CSL2-0 control pins. See Table 2 for selections based in CSL2-
0 pin settings.
Quiet Code
The PCM serial port can be made to send quiet code to the decoder and receive filter path by setting the RxMute
pin high. Likewise, the PCM serial port will send quiet code in the transmit path when the
Figure 2 - Table 2: Bit Clock Rate Selection
TxMute pin is high. When either of these pins are low their respective paths function normally. The -Zero entry of
Table 1 is used for the quiet code definition.
