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.","metaTitle":"CDCEL937PWR Clock Synthesizer, 230 MHz, 20-TSSOP","metaDescription":"TI CDCEL937PWR is a 3-PLL VCXO clock synthesizer with 1:7 LVCMOS outputs, 230 MHz max, 1.7-1.9V supply, -40°C to 85°C.
