Zarlink Semiconductor, Inc. was acquired by Microsemi Corporation in October 2011.
Features
• Next Generation ZL880 VoicePort Family with
Enhanced Features and Perfo rmance
- Same API interface as the VE880 Series
- 35% lower BOM cost than previous generation
• Complete BORSCHT Functions for Two FXS
Channels in a Single 64-Pin QFN Packag e
-Battery feed, Over-voltage support, integrated
Ringing, line Supervision, Codec, Hybrid
(2W/4W), and Test
• Integrated Power Management
- Switching power supply tracks line voltage
minimizing active and ringing power dissipation
- Low Power Idle Mode with 45mW consumption
- Internal FET drive circuit for lower BOM count
- Integrated real-time power monitoring tool
• Ringing
- 5 REN with pin for pin comp atible 100-V
(ZL88701) and 150-V (ZL88702) devices
- Up to 140-VPK internal sinusoidal or trapezoidal
ringing with programmable DC offset
- Adaptive ringing for lower power
• Worldwide Programmability
- Input impedance, balance impedance, gain
- DC feed voltage and current limit
- Ringing frequency, voltage and current limit
- G.711 µ-law, A-law, or 16 bit linear coding
- Call progress tone and Caller ID generation
- Sample coefficients for more than 70 countries
• Pin-Selectable PCM/MPI or ZSI Interfaces
- SPI Mode 0 and 3 support and no inter by te CS
off time. Also supports legacy MPI Interface.
- ZSI Mode for a smaller number of interface
signals to the host and less expensive isolation
• VoicePath SDK and VP-API-II Software
Av ailable to Implement FXS Func tions
• VeriVoice Software Suites Available for
Manufacturing and Subscriber Loop Testing
- Utilizes integrated test tool box
Applications
• DSL Residential Gateways and Integrated
Access Devices (IADs)
• Cable eMTAs
• PON Single Family Units (SFUs)
• Fiber to the Premise/Home/Building (FTTx)
Multiple Dwelling Units (MDUs)
Description
The Microsemi® ZL88701/702 Dual Channel Tracking
Battery Wideband VoicePort Device provides complete
BORSCHT functions for two telephone line FXS ports.
This device is part of the new ZL880 Series featuring
enhanced functionality, lower BOM cost, and greater
power efficiency, while maintaining software
compatibility with the industry leading VE880 Series.
