Product details

230 MHz clock synthesizer with 1:7 fan-out

The CDCEL937PW is a three-PLL VCXO clock synthesizer from Texas Instruments that generates up to 230 MHz on any of its seven LVCMOS outputs from a single LVCMOS or crystal input. The PLL can be bypassed, letting the reference clock pass straight through for low-jitter paths or test modes.

Industrial temperature and 20-TSSOP package

Housed in a 20-TSSOP (4.40 mm width), it reflows cleanly under a hot-air station — the 0.65 mm pitch is forgiving enough for hand rework if you keep the tip clean and the profile gentle.

Frequently asked questions

What is the maximum output frequency of the CDCEL937PW?

The maximum output frequency is 230 MHz on any of the seven LVCMOS outputs.

What supply voltage does the CDCEL937PW need?

It requires a 1.7V to 1.9V supply — typically a 1.8V rail. It will not run from 3.3V or 2.5V.

Is the CDCEL937PW a good alternative to the CD74HCT7046AE?

Not directly — the CD74HCT7046AE is a single PLL in a through-hole package running at 38 MHz from a 4.5V supply. The CDCEL937PW is a surface-mount 3-PLL synthesizer with seven outputs at 230 MHz on a 1.8V rail. They serve different clock domains.
