The integrated PLL includes a bypass path — when bypassed, the input clock passes through with minimal added jitter, useful for system test modes or low-latency paths. The 1:7 input-to-output ratio means a single reference can feed multiple clock domains, reducing the external oscillator count on the board. ## Supply rail and temperature — design constraints The device operates from a 1.7V to 1.9V supply, which aligns with 1.8V logic families common in low-power FPGAs, SoCs, and memory interfaces. The 20-TSSOP package (4.40 mm width) is a fine-pitch surface-mount footprint; verify the land pattern matches the supplier device package drawing before layout.","metaTitle":"Texas Instruments CDCE937PWRG4 PLL Clock Generator, 230 MHz","metaDescription":"Texas Instruments CDCE937PWRG4 PLL clock generator with bypass, 230 MHz max output, 1.7V–1.9V supply, LVCMOS/crystal input, 1:7 outputs.

The device accepts LVCMOS inputs and its supply range of 1.7V to 1.9V directly covers the 1.8V LVCMOS logic level. The input threshold scales with the supply, so a 1.8V LVCMOS signal is within the guaranteed VIH/VIL window."},{"question":"What is the maximum output frequency of CDCE937PWRG4?","answer":"The maximum output frequency is 230 MHz. This ceiling applies to any of the seven LVCMOS outputs when the PLL is engaged.
