MK74CG117BFLF

Overview

The MK74CG117BFLF is a monolithic CMOS clock generator manufactured by Renesas Electronics (formerly IDT). It integrates an on-chip PLL and provides 16 low-skew outputs. The device generates output clocks up to 100 MHz from a simple crystal or clock input, eliminating the need for external oscillators. It operates at a supply voltage of 3.14 V to 3.47 V with a typical current of 63 mA at 50 MHz. The component features output skew less than 250 ps and supports configurable frequency modes.

Feature Summary

• Integrates an on-chip PLL to generate high-speed clocks up to 100 MHz
• Provides 16 low-skew outputs with rising edge skew under 250 ps
• Supports flexible configuration: 16 full speed, 12 full/4 half, or 8 full/8 half frequencies
• Includes tri-state mode for output enable control

Applications

• Communications systems requiring multiple synchronized high-speed clocks
• Data acquisition systems needing precise clock distribution
• Industrial control applications utilizing buffered reference outputs

Procurement Notes

Verify RoHS compliance status as non-green parts reached end-of-life on May 13, 2010. Confirm package type availability, as the LF suffix indicates tube packaging. Check for product discontinuance notices regarding the original manufacturer IDT before procurement planning.

Selection Notes

Select based on required operating temperature range; the FLF suffix denotes the commercial grade (0°C to +70°C), while BFILF indicates industrial grade (-40°C to +85°C). Ensure external termination resistors are included in the design to match source impedance and minimize reflections. Verify crystal load capacitance requirements using the internal capacitor values provided in the datasheet.

Part Context

This component belongs to the MK74CG117 family of clock generators. The specific part number MK74CG117BFLF identifies the commercial temperature variant packaged in tubes. Related variants include the industrial temperature version MK74CG117BFILF and tape-and-reel options ending in FT.

Replacement Considerations

Direct replacements include MK74CG117BFILF for industrial temperature operation. For tape-and-reel packaging, consider MK74CG117BFLFT or MK74CG117BFILFT. Note that the original manufacturer IDT was acquired by Renesas Electronics.
