LE88266TQC Description

Short technical summary and product information.

The Microchip Technology LE88266TQC is a dual-channel Automatic Battery Switching (ABS) VoicePort device designed for telecom applications. It provides a complete BORSCHT functions for two channels in a single device, integrating power management and high voltage switching regulator controllers.

 

This IC supports a wide voltage range from 4.75V to 35V and features a PCM interface, with pin-selectable options for MPI or GCI. It offers worldwide programmability for input impedance, balance impedance, gain, DC feed voltage, current limit, ringing frequency, voltage, and current limit. The device supports 12 kHz and 16 kHz metering, programmable supervision thresholds, and up to 110-Vpk internal balanced ringing.

 

Key features include a powerful signal generator, universal Caller ID generation, and the capability to produce up to 4 simultaneous tones. It integrates a 150 mW 3-V relay driver and supports G.711 µ-law, A-law, or 16-bit linear coding with a wideband 16 kHz sampling mode. The LE88266TQC is available in a small footprint 64-pin QFN package with surface mount mounting type.

 

Applications for this device include voice-enabled Cable EMTA’s, DSL Gateways and IAD’s, Fiber to the Building/Home (FTTB/H) Optical Network Terminals (ONT), and Wireless Local Loop (WLL) PBX systems. VoicePath™ API-II software is available to implement FXS functions, and the device supports calibration and line configuration via the VoicePath Profile Wizard.
