MK1575-01GTR

Overview

The MK1575-01GTR is a clock recovery Phase-Locked Loop (PLL) designed for cost-sensitive video and telecom applications. It accepts low-frequency reference clocks to generate high-frequency data or graphics pixel clocks. The device operates on a single 3.3V supply with a voltage range of 3.15V to 3.45V. It features selectable internal feedback dividers for standard frequencies, supports up to 80MHz output, and includes power-down and tri-state modes. Packaged in a 16-pin TSSOP, it offers long-term jitter performance under 2ns over a 10µsec period.

Feature Summary

• Clock recovery PLL optimized for video and telecom frequency synthesis
• Selectable internal feedback divider for standard T/E and video clock modes
• Long-term output jitter less than 2 nsec over a 10 µsec period
• External loop filter support for customizable bandwidth and damping

Applications

• Video genlock and synchronization
• Telecom T/E clock generation
• Graphics pixel clock synthesis
• Cost-sensitive clock recovery systems

Procurement Notes

Verify the specific suffix requirements for packaging and temperature grade. The 'TR' suffix indicates Tape and Reel packaging. Confirm lead-free status if required, as non-green parts have reached End-of-Life. Check current availability as this component may be subject to discontinuation notices from the manufacturer.

Selection Notes

Select based on required output frequency and input reference clock. Use the Detailed Mode Selection Table to determine FS2:0 pin settings. Ensure external loop filter components are chosen to meet specific jitter and damping factor requirements. Verify that the 16-TSSOP package fits the PCB layout constraints.

Part Context

This part belongs to the MK1575-01 family of clock recovery PLLs manufactured by IDT, now part of Renesas Electronics. The GTR variant specifically denotes the commercial temperature range (0°C to +70°C) and Tape and Reel packaging format. It is distinct from industrial variants which carry an 'I' suffix.

Replacement Considerations

For lead-free versions in tape and reel, consider MK1575-01GLFTR. Industrial temperature range equivalents include MK1575-01GITR or MK1575-01GILFTR. Note that non-green parts have reached End-of-Life.
