SI2415-C-FSR

Overview

The SI2415-C-FSR is a system-side component of the Skyworks ISOmodem family, designed for embedded modem applications. It supports data rates up to 33.6 kbps and operates with a supply voltage range of 3.0 V to 3.6 V. The device features an integrated Direct Access Arrangement (DAA) providing over 6000 V capacitive isolation. It supports UART, SPI, or parallel host interfaces and utilizes a 4.915 MHz clock input frequency. Operating within a commercial temperature range of 0°C to +70°C, it consumes approximately 17 mA during active operation. The component is housed in a 16-pin SOIC package.

Feature Summary

• Integrated DAA technology eliminates external DSP, codec, transformer, and hybrid components
• Supports global telephone line interface compliance with parallel phone detection
• Firmware upgradeable with EEPROM interface and AT command set support

Applications

• Set-top boxes
• Point-of-sale terminals
• Text and video telephones
• Digital video recorders
• Remote monitoring systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout and packaging details. Confirm that the Si2415 is paired with the appropriate line-side device, such as the Si3018, as specified in the chipset combination guide. Ensure environmental specifications match the target application requirements before procurement.

Selection Notes

Select this model when a compact 16-pin solution is required for embedded modem designs. Verify compatibility with the intended host interface mode, whether UART, SPI, or parallel. Ensure the design accommodates the necessary clocking options, such as the 4.915 MHz oscillator, and check that the supported protocol speeds align with the application's data rate needs.

Part Context

This component belongs to the ISOmodem family, which includes the Si2457, Si2434, and Si2404 variants. These devices share similar architectural features but differ in maximum data speeds and supported protocols. The Si2415 specifically targets applications requiring speeds up to 33.6 kbps, distinguishing it from higher-speed counterparts like the Si2457.

Replacement Considerations

Consult the manufacturer's datasheet for officially recommended substitutes. Cross-reference pin assignments and electrical characteristics carefully if considering alternative models within the same family or from other manufacturers.
