MK2703SILFTR

Overview

The MK2703SILFTR is a PLL audio clock synthesizer manufactured by Renesas Electronics. It operates within an SOIC-8 surface-mount package and supports input frequencies up to 27MHz. The device utilizes a Phase Locked Loop architecture to generate precise clock signals, functioning as a jitter cleaner for audio applications. It is designed for use in multimedia systems requiring stable clock generation from crystal or clock inputs.

Feature Summary

• PLL-based audio clock synthesis with jitter cleaning capabilities
• Supports standard MPEG sampling rates including 32 kHz, 44.1 kHz, 48 kHz, and 96 kHz
• Operates on a single supply voltage of 3.3V or 5V
• Utilizes low-power sub-micron CMOS process technology

Applications

• Set-top box clock generation
• Multimedia system audio clocking
• Replacement for discrete oscillators and VCXOs in audio circuits

Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock this part number. Verification of current lifecycle status and alternative sourcing options is required before procurement planning.

Selection Notes

Select this component for fixed-frequency audio clock synthesis where low jitter is critical. Ensure the design accommodates the 8-SOIC package dimensions. Verify that the required supply voltage matches the 3.3V or 5V operational range specified for this device.

Part Context

The MK2703SILFTR belongs to the MK2703 series of clock synthesizers. It is functionally related to variants such as the MK2703SLFTR, differing primarily in packaging or temperature grade specifications. The suffix 'LFTR' indicates a lead-free tape and reel packaging format.

Replacement Considerations

Due to the EOL status, direct substitutes are not explicitly confirmed in public documentation. Designers should evaluate other members of the MK2703 family or consult the manufacturer for recommended obsolescence management strategies.
