Product details

Three-PLL VCXO clock synthesizer for multi-output clock trees

The Texas Instruments CDCEL937PWR is a clock/frequency synthesizer built around three PLLs with VCXO capability, each PLL featuring a bypass mode. The 230 MHz maximum output frequency covers most FPGA reference clocks, SerDes reference inputs, and ADC sample clocks. The 1:7 input-to-output ratio means one clean reference fans out to seven loads — enough to clock an entire FPGA bank or a multi-ASIC board without extra fanout buffers.

ROHS3 compliant. For new designs, this part is safe to specify without worrying about a sudden obsolescence-driven redesign.

Frequently asked questions

What is the maximum frequency of CDCEL937PWR?

The maximum output frequency is 230 MHz. That covers 156.25 MHz Ethernet references, 125 MHz DDR3/4 controller clocks, and 100 MHz PCIe references from the same PLL bank.

Is CDCEL937PWR compatible with 1.8V logic?

Yes. The supply voltage range is 1.7 V to 1.9 V, which directly matches a 1.8 V nominal rail. Inputs and outputs are LVCMOS, so they swing rail-to-rail at 1.8 V.

What is the replacement or equivalent for CDCEL937PWR?

No direct pin-compatible replacement is listed in the official record. The CD74HCT7046AE is a different class — through-hole, 38 MHz, 4.5 V supply, 1:2 ratio — not a functional substitute for this 230 MHz, 1.8 V, 1:7 synthesizer.
