MK2703BSILF

Overview

The MK2703BSILF is a PLL audio clock synthesizer manufactured by Renesas Electronics (formerly ICS/IDT). It utilizes a 27 MHz crystal or clock input to generate a buffered reference clock and a selectable audio clock. The device supports MPEG sampling rates of 32 kHz, 44.1 kHz, 48 kHz, and 96 kHz via hardware selection pins. Operating on a 3.3 V or 5 V supply, it features zero ppm synthesis error and low jitter performance. The component is housed in an 8-pin SOIC package and is rated for the industrial temperature range of -40°C to +85°C.

Feature Summary

• Patented analog PLL technique providing zero ppm synthesis error across all generated frequencies
• Hardware-selectable audio clock outputs: 8.192 MHz, 11.2896 MHz, 12.288 MHz, and 24.576 MHz
• Supports fundamental mode 27 MHz crystals or direct clock inputs
• Industrial temperature rating (-40°C to +85°C) with RoHS compliant lead-free packaging

Applications

• Set-top box systems
• Multimedia audio processing circuits
• Systems requiring precise MPEG sampling rate generation

Procurement Notes

Verify that the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C) and 'LF' indicates lead-free compliance. Confirm the 'S' designation corresponds to the 8-pin SOIC package. Check current availability status as this component family may be subject to discontinuation notices from the manufacturer.

Selection Notes

Select this part when replacing oscillators or VCXOs in multimedia designs to reduce board space. Ensure the design accommodates external load capacitors calculated based on the crystal's specified load capacitance (CL), accounting for the device's internal ~16 pF capacitance. Verify power supply stability as decoupling capacitors are required near the VDD pin.

Part Context

This component belongs to the MK2703 series of PLL audio clock synthesizers originally developed by Integrated Circuit Systems (ICS) and later acquired by IDT, now part of Renesas Electronics. The 'MK2703BSILF' variant specifically denotes the industrial grade version in tape-and-reel packaging, distinguishing it from commercial grades and tube-packaged options within the same functional family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer for current lifecycle status and potential obsolescence management strategies.
