Z0220112VSCR4078

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 and complies 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, consuming 50 mA typically in active mode and less than 1% in sleep mode. It features a 44-pin PQFP or PLCC package and includes HDLC framing, programmable tone detectors, and adaptive equalization.

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 the need for external SIO devices
• Programmable bi-quad tone detectors for call-progress monitoring

Applications

• Embedded modem applications requiring space and power efficiency
• Data communication over Public Switched Telephone Network (PSTN)
• Industrial control systems utilizing dial-up connectivity

Procurement Notes

Verify the specific package variant required, as the Z02201 is available in both 44-pin PQFP and PLCC configurations. Confirm that the design utilizes a single +5 VDC power supply within the specified voltage range of 4.5 V to 5.5 V. Ensure the host microprocessor interface matches the TTL-compatible parallel or serial synchronous requirements defined in the datasheet.

Selection Notes

Select the Z02201 when a complete V.22bis solution with integrated analog front-end is needed. It is suitable for designs requiring direct connection to a Data Access Arrangement (DAA) via transformer. Consider this component for applications needing programmable tone generation and detection without external digital signal processing overhead.

Part Context

Zilog developed the Z02201 as a specialized synchronous modem chip for embedded systems. It consolidates data pump functions and analog conversion into a single silicon die, reducing the bill of materials compared to discrete solutions. The device targets markets where low power consumption and compact form factors are critical constraints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Zilog or Microchip Technology technical support for current equivalent recommendations.
