MK2732-06GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The MK2732-06GTR is a low-cost, low-jitter clock synthesizer and VCXO manufactured by Integrated Device Technology (IDT), now part of Renesas Electronics. Packaged in a 16-pin TSSOP, it integrates a Voltage Controlled Crystal Oscillator and PLL to replace discrete components. It accepts a 10–14 MHz pullable crystal input and generates up to three output clocks with zero ppm synthesis error. The device operates on a 5 V core supply and supports 3.3 V or 5 V I/O levels, featuring a 0–3 V tuning voltage for ±100 ppm frequency variation.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Integrated VCXO with 200 ppm pull range (±100 ppm) controlled by 0–3 V input
• Zero ppm frequency synthesis error across all generated clocks
• Supports full CMOS output swings with 25 mA drive capability at TTL levels
• Operates on 5 V core voltage with flexible 3.3 V or 5 V I/O interface

Clock Generators, PLLs, Frequency Synthesizers Applications

• xDSL chipsets
• MPEG2 decoders
• Set-top boxes
• Communications equipment requiring low jitter clock synthesis

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer origin as this component was originally produced by IDT before its acquisition by Renesas. Confirm that the 'GTR' suffix indicates Tape and Reel packaging for the commercial temperature version. Check for End-of-Life notices regarding non-green parts, which were scheduled for discontinuation in May 2010.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the MK2732-06GTR for commercial applications (0°C to +70°C) requiring tape and reel packaging. For industrial temperatures (-40°C to +85°C), consider the GI or GILF variants. Ensure the design utilizes a pullable crystal between 10 and 14 MHz and provides appropriate decoupling capacitors (0.01 µF and 0.1 µF) near power pins.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the MK2732 family of low phase noise VCXOs and multipliers. The 'GTR' suffix specifically denotes the Tape and Reel shipping format for the lead-free, commercial temperature grade variant. It serves as a direct replacement for discrete VCXO and multiplier combinations in cost-sensitive digital communication designs.
