MSM7533V
2ch Single Rail CODEC
FEDL7533V-01
Issue Date: Jun. 22, 2012
GENERAL DESCRIPTION
The MSM7533V is two-channel CODEC CMOS ICs for voice signals ranging from 300 to 3400 Hz.
These devices contain filters for A/D and D/A conversion.
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 MSM7533V is best suited for an analog interface to an echo canceller DSP used in digital telephone
terminals, digital PABXs, and hands free terminals.
FEATURES
• Single power supply: +5 V
• Power consumption
Operating mode: 35 mW Typ. 74 mW Max. VDD = 5 V
Power save mode: 7 mW Typ. 16 mW Max. VDD = 5 V
Power down mode: 0.05 mW Typ. 0.3 mW Max. VDD = 5 V
• ITU-T Companding law
MSM7533V: μ/A-law pin selectable
• Built-in PLL eliminates a master clock
• The PCM interface can be switched between 2 channel serial/parallel
