LE9662WQCT

Telecom Overview

The LE9662WQCT is a dual-channel telecom interface integrated circuit manufactured by Microchip Technology. It supports ZSI (Zero Series Interface) and ABS (Analog Battery Signaling) protocols for line interface applications. The device is housed in a 56-pin VQFN package and is supplied in tape and reel format with a factory pack quantity of 2700 units. This component is designed for robust telecommunication line signaling and interface management.

Telecom Feature Summary

• Dual-channel architecture supporting simultaneous line interface operations
• Integrated support for ZSI and ABS signaling protocols
• Compact surface-mount VQFN-56 packaging for space-constrained designs

Telecom Applications

• Telecommunications line interface modules
• ZSI-based subscriber line equipment
• ABS signaling systems in central office hardware

Telecom Procurement Notes

Verify the specific suffix WQCT against official Microchip documentation to confirm package type, temperature range, and reel specifications. Ensure compatibility with existing PCB footprints for the VQFN-56 form factor. Cross-reference the Mouser part number 494-le9662wqct for accurate sourcing details and current availability status from authorized distributors.

Telecom Selection Notes

Select this component when designing dual-channel telecom interfaces requiring ZSI or ABS protocol support. Confirm that the VQFN-56 package dimensions align with the target board layout. Evaluate thermal requirements for the operating environment, as the datasheet defines specific junction temperature limits. Compare against single-channel alternatives if only one port is required.

Telecom Part Context

This part belongs to the LE96xx series of telecom interface ICs from Microchip Technology. It complements other models like the LE9622RQCT, which offers similar functionality but with a different pin count and protocol focus. The series targets high-reliability communication infrastructure requiring standardized line interface capabilities.
