Z0220112VSGR3470

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 12.288 MHz oscillator frequency and provides both parallel and serial interface options for host microprocessor connectivity.

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 tone detectors and generators for call-progress monitoring

Applications

• Embedded modem applications requiring space and low power efficiency
• PSTN-based communication systems
• Data Terminal Equipment (DTE) interfaces with error control

Procurement Notes

Verify the specific package variant required, as the Z02201 is available in 44-pin PQFP and PLCC configurations. Confirm that the ordering suffix corresponds to the desired package type and temperature range. Ensure compatibility with standard 8-bit microprocessors for the parallel interface or verify serial interface timing requirements if using the synchronous port.

Selection Notes

Select this component for applications needing a complete V.22bis solution without external DSPs. The integrated equalizers handle diverse line conditions. Consider the parallel interface for direct access to registers and RAM, or the serial interface for simplified data transfer. Verify power supply stability and crystal specifications for the 12.288 MHz clock requirement.

Part Context

The Z02201 belongs to the Z02201 series of V.22bis data pumps manufactured by Zilog. It is designed as a standalone modem chip that simplifies design by integrating modulation, demodulation, filtering, and A/D-D/A conversion functions into a single silicon die.
