MK2716STR

Overview

The MK2716STR is a clock synthesizer manufactured by Renesas Electronics Corporation, originally developed by IDT. It generates 74.175824 MHz or 74.25 MHz clocks for HDTV systems using a 27 MHz input. The device features zero ppm synthesis error and operates on a 3.0 V to 5.5 V supply. It utilizes an analog PLL and sub-micron CMOS process. The component is packaged in an 8-pin SOIC (0.154" width) and supports surface mount installation. Operating temperature ranges from 0°C to +70°C.

Feature Summary

• Zero ppm synthesis error for exact display locking
• Accepts 27 MHz crystal or clock input
• Generates 74.175824 MHz or 74.25 MHz outputs
• 25 mA output drive capability at TTL levels

Applications

• HDTV system clock generation
• Multimedia applications requiring precise video timing
• Oscillator replacement in set-top boxes

Procurement Notes

Verify the manufacturer status as the original developer was IDT, now part of Renesas. Confirm RoHS compliance details, noting that non-green parts reached end-of-life on 5/13/10. Ensure the specific 'STR' suffix corresponds to tape and reel packaging in current distributor catalogs.

Selection Notes

Select this component when a fixed 74.176 MHz or 74.25 MHz output is required from a 27 MHz reference. It replaces multiple crystals and oscillators. For lower jitter requirements like SDI, consider the ICS664 instead. Ensure PCB traces between the crystal and device are short to minimize stray capacitance.

Part Context

The MK2716 belongs to the IDT HDTV Clock Synthesizer family. It is designed to eliminate external VCXOs and crystals from boards. The STR suffix indicates a Tape and Reel shipping configuration within the 8-pin SOIC package family.
