MK2703BSILFTR

Overview

The MK2703BSILFTR is a PLL audio clock synthesizer manufactured by Renesas Electronics Corporation, utilizing ICS technology. It operates within an ambient temperature range of -40°C to +85°C and accepts a 27 MHz crystal or clock input. The device provides a buffered 27 MHz reference output and a selectable audio clock output via two digital select pins (S1, S0). Supported audio frequencies include 8.192 MHz, 11.2896 MHz, 12.288 MHz, and 24.576 MHz. It functions on a supply voltage of 3.13 V to 5.5 V with a maximum operating current of 10 mA.

Feature Summary

• Patented zero ppm synthesis error for all generated clocks
• Supports MPEG sampling rates including 8.192 MHz, 11.2896 MHz, 12.288 MHz, and 24.576 MHz
• RoHS compliant lead-free packaging in an 8-pin SOIC package
• Industrial temperature rating (-40°C to +85°C)

Applications

• Set-top box systems
• Multimedia systems
• Audio clock generation requiring frequency locking

Procurement Notes

Verify the industrial temperature grade suffix 'I' and lead-free status 'LF' against the datasheet ordering table. Confirm the 'TR' suffix indicates tape and reel shipping. Check manufacturer announcements for end-of-life status, as previous variants have been discontinued.

Selection Notes

Select this variant specifically for industrial temperature environments (-40°C to +85°C). Ensure the application requires one of the four fixed audio clock outputs determined by S1/S0 pin states. Verify that the 27 MHz input source matches the device's fundamental mode crystal requirement.

Part Context

This component belongs to the MK2703B family of PLL audio clock synthesizers originally developed by Integrated Circuit Systems (ICS) and later acquired by IDT, now part of Renesas Electronics. The 'BSILFTR' designation specifies the commercial base die, industrial temperature range, lead-free packaging, and tape-and-reel delivery method.
