MK74CG117BFTR

Overview

The MK74CG117BFTR is a monolithic CMOS high-speed clock generator featuring an on-chip PLL and 16 low-skew outputs. It operates at 3.3 V ±5% with an industrial temperature range of -40°C to +85°C. The device generates output clocks up to 100 MHz from a simple crystal or clock input, utilizing built-in multipliers (2x to 5x) or dividers. Output skew is less than 250 ps on rising edges. It supports tri-state mode for output enable and includes a buffered reference output. The component is housed in a 48-pin SSOP package.

Feature Summary

• On-chip PLL generates output clocks up to 100 MHz from a simple crystal or clock input
• 16 low-skew outputs with skew less than 250 ps on rising edges
• Configurable as 16 full frequency, 12 full/4 half, or 8 full/8 half frequency outputs
• Tri-state mode for Output Enable function

Applications

• Communications systems requiring large numbers of high-speed clocks
• Systems eliminating oscillators and low skew buffers
• Clock distribution networks using single inexpensive low-frequency crystals

Procurement Notes

Verify the 'LF' suffix status regarding RoHS compliance and EOL notices. The datasheet indicates non-green parts faced EOL on 5/13/10. Confirm current manufacturing status and lead times directly with Renesas Electronics or authorized distributors, as availability may be restricted.

Selection Notes

Select this part when 16 synchronized low-skew outputs are required from a single source. Ensure the application voltage is 3.3 V ±5%. For frequencies above 83.3 MHz, all outputs must run at the same frequency. Verify thermal requirements, as power dissipation increases with output load capacitance and frequency.

Part Context

This component belongs to the IDT™ 16 Output Low Skew Clock Generator family. It integrates clock synthesis and mode select circuitry to provide multiple clock phases from a single input. The 'BFTR' suffix denotes the 48-pin SSOP package, tape and reel shipping format, and industrial temperature rating (-40°C to +85°C).

Replacement Considerations

Public confirmed substitute part numbers: MK74CG117BFILF (Tube), MK74CG117BFLF (Tube), MK74CG117BFLFT (Reel). These share identical electrical specifications and pinouts but differ in packaging or RoHS compliance status.
