Description : QUAD NON-PROGRAMMABLE PCM codec View


The IDT821024 is a single-chip, four channel PCM codec with on-chip filters. The device provides analog-to-digital and digital-to-analog conversions and supports both a-law and μ−law companding. The digital IDT821024 provides the necessary transmit and receive filtering for voice telephone circuit to interface with time-division multiplexed systems. All of the digital filters.are performed in digital signal processors operating from an internal clock, which is derived from MCLK. The fixed filters.set the transmit and receive gain and frequency response.

Description : PCM codec–Filter Mono–Circuit View

Legacy Device: Motorola MC145506

The ML145506 is a per channel codec–filter PCM mono–circuit. This device performs the voice digitization and reconstruction, as well as the band limiting and smoothing required for PCM systems. This device has HCMOS compatible digital outputs and supplements the Lansdale ML145502 – ML145505 series of PCM codecfilters. The ML145506 is functionally similar to the ML145502. It is designed to operate in both synchronous and asynchronous applications and contain an on–chip precision reference voltage. The ML145506 is offered in a 22–pin package and has the capability of selecting from three peak overload voltages (2.5 V, 3.15 V, and 3.78 V).

ML145506 Features
• 22–Pin Package, HCMOS Output Version of ML145502
• Selectable Peak Overload Voltages (2.5 V, 3.15 V, 3.78 V)
