... Designed especially for a single-power supply and low-power applications, these devices contain two-channel AD/DA converters in a single chip and achieve a reduced footprint and a reduced number of external components. The MSM7533 and MSM7534 are best suited for an analog interface to an echo canceller DSP used in digital telephone terminals, digital PABXs, and hands free terminals. FEATURES • ...

... However, if the frequency characteristic of the system used is not strictly specified, this device can operate in the range of 6 kHz to 9 kHz, but the electrical characteristics in this specification are not guaranteed. Setting this signal to logic "1" or "0" drives both transmit and receive circuits to power saving state. MSM7533H/7533V/7534 6/18 ...

... ALAW Control signal input of the companding law selection. Provides only for the MSM7533VRS/MSM7533VGS-K. The CODEC will operate in the m-law when this pin logic "0" level and the CODEC will operate in the A-law when this pin logic "1" level. The CODEC operates in the m-law if the pin is left open, since this pin is internally pulled down ...
