ML7033
Dual-Channel Line Card CODEC
FEDL7033-04
Issue Date: Oct. 13, 2011
GENERAL DESCRIPTION
The ML7033 is a 2-channel PCM CODEC CMOS IC designed for Central Office (CO) and Customer Premise
Equipment (CPE) environments. The ML7033 device contains 2-channel analog-to-digital (A/D) and
digital-to-analog (D/A) converters with multiplexed PCM input and output. The ML7033 is designed for
single-rail, low power applications. The high integration of the ML7033 reduces the number of external
components and overall board size. The ML7033 is best suited for line card applications and provides an easy
interface to subscriber line interface circuits (SLIC’s), in particular the Intersil RSLICTM series.
