Product details

1:4 clock buffer for LVCMOS distribution

The LMK1C1104DQFR is a single-channel 1:4 fanout clock buffer from Texas Instruments, accepting LVCMOS input and delivering LVCMOS outputs up to 250 MHz. It's the part you reach for when a master clock needs to drive four loads without loading the source oscillator.

Supply flexibility across three rails

The buffer operates from three distinct supply ranges: 1.71V to 1.89V, 2.375V to 2.625V, and 3.135V to 3.465V. That covers 1.8V, 2.5V, and 3.3V nominal rails — so the same BOM line works across a multi-rail board without a level translator on the clock path.

Industrial temperature and 8-WSON package

The 8-WSON package (2x2 mm, supplier device package 8-WSON) keeps the footprint small — useful when board space is tight near the processor or FPGA clock input.

Frequently asked questions

Where can I buy LMK1C1104DQFR and get a quote?

The LMK1C1104DQFR is an active Texas Instruments part. Submit an RFQ with your target quantity and lead-time window; we confirm availability and current pricing at quote time. No stock-holding claim — sourced per order.

Is LMK1C1104DQFR compatible with a 1.8V supply?

Yes. The buffer's supply range includes 1.71V to 1.89V, which covers a nominal 1.8V rail. The LVCMOS input and output levels track the supply voltage.
