CPC2400E

Overview

The CPC2400E is a 2400 baud embedded modem module designed for PSTN data communications. It integrates a Data Access Arrangement (DAA), V.22bis data pump, and microcontroller on a 1.00" x 2.50" PCB. The module operates from a single +5V supply with idle current of 5-10 mA and active current of 70-100 mA. It supports V.22bis, V.23, and V.22 protocols via a standard V.24 TTL interface. Key electrical parameters include a dielectric withstand voltage of 1000 V rms, ringing voltage of 22-30 V rms, and line matching impedance of 600 ohms.

Feature Summary

• FCC Part 68 approved with user transferrable registration number
• Supports full duplex 2400bps communication over PSTN
• Includes integrated DAA with surge protection and hookswitch control
• Operates in low power sleep mode with wake-on-ring capability

Applications

• Vending and gaming machines
• Set top box back channel communications
• Utility meters and remote telemetry
• Point of sale terminals
• Remote diagnostics and monitoring

Procurement Notes

Verify the specific revision suffix against the manufacturer's latest documentation to ensure compatibility with required firmware features. Confirm that the end-product design adheres to FCC Part 68 layout guidelines, including trace isolation and UL 94V-0 PCB standards. Ensure the host system provides a stable +5V supply within the specified tolerance range for reliable operation.

Selection Notes

Select this module for applications requiring certified PSTN connectivity without external modem components. It is suitable for space-constrained designs due to its small footprint. Verify that the host system can support the required V.24 serial interface signals. Consider the environmental temperature range of 0 to 70 degrees Celsius when designing the enclosure.

Part Context

The CPC2400E belongs to IXYS Integrated Circuits Division's embedded modem family. It serves as a complete solution for connecting digital devices to analog telephone networks. The module simplifies compliance with telecommunications regulations by incorporating necessary line interface circuitry and regulatory approvals directly onto the board.

Replacement Considerations
