307M-02LFT

Overview

The Renesas 307M-02LFT is a serially programmable clock generator housed in a 16-pin SOIC package. It generates output frequencies from 6 MHz to 200 MHz using an input crystal or clock between 5 MHz and 27 MHz. The device features two configurable LVCMOS outputs with low jitter (50 ps typical). It supports on-the-fly reprogramming via a 3-wire interface, locking to new frequencies within 10 ms. Operating voltage ranges from 3.0 V to 5.5 V, with a drive capability of 25 mA at TTL levels.

Feature Summary

• Serially programmable via 3-wire interface for flexible frequency generation
• ICS307-02 variant provides default x1 clock output at startup
• Low jitter performance with smooth duty cycle transitions near 50%
• Power-down tri-state mode via PDTS pin for energy efficiency

Applications

• General-purpose clock generation for digital systems
• Replacing custom quartz crystals in space-constrained designs
• Systems requiring dynamic frequency adjustment during operation

Procurement Notes

Verify the component status as discontinued through official manufacturer channels. Confirm that the 'LF' suffix indicates a lead-free, RoHS-compliant configuration. Ensure compatibility with existing board layouts for the 16-SOIC package before procurement.

Selection Notes

Select this model over the ICS307-01 if a default clock output at power-up is required for system initialization. Verify that the operating temperature range matches the application environment, as industrial versions are available separately. Ensure the input frequency falls within the 5–27 MHz range for proper PLL locking.

Part Context

This component belongs to the ICS307 series of serially programmable clock sources manufactured by Renesas Electronics Corporation (formerly IDT). The series includes variants like the ICS307-01 and ICS307-02, differentiated primarily by their power-up default states. The 307M-02LFT specifically denotes the commercial temperature range version in tape-and-reel packaging.

Replacement Considerations

Public confirmed substitute part numbers: None.
