Z0220112VEGR4078

Overview

The Z02201 is a synchronous single-chip V.22bis data pump with an integrated Analog Front-End (AFE). It supports full-duplex throughput up to 2400 bps over dial-up lines, complying with ITU V.22bis, V.23, V.22, V.21, Bell 212A, and Bell 103 standards. The device operates on a single +5 VDC supply with typical current consumption of 50 mA. It features a 44-pin PLCC or LQFP package and includes HDLC framing, programmable tone detectors, and adaptive equalization. The internal oscillator runs at 12.288 MHz.

Feature Summary

• Integrated AFE with full-duplex voice band capabilities and 12-bit resolution
• Supports multiple modulation schemes including FSK, DPSK, and QAM
• Built-in HDLC framing eliminates external SIO requirements
• Programmable bi-quad tone detectors for call-progress monitoring

Applications

• Embedded modem applications requiring space and low power efficiency
• PSTN communication systems utilizing V.22bis or Bell standards
• Data terminal equipment (DTE) interfaces with error control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and temperature range. Ensure compatibility with the host microprocessor interface requirements before integration. Check for moisture sensitivity handling procedures during storage and assembly.

Selection Notes

Select this component for designs requiring a complete modem solution without external DSPs. Confirm that the host system can support the parallel or serial interface modes. Evaluate power budget constraints as sleep mode reduces consumption significantly below operating levels.

Part Context

This part belongs to the Z02201 series of V.22bis data pumps manufactured by ZiLOG. It is designed as a drop-in replacement for legacy discrete modem solutions, consolidating modulation, demodulation, and analog filtering into a single silicon die.
