Product details

PLL clock generator with bypass — one input, nine outputs

The Texas Instruments CDCE949PWRG4 is a PLL-based clock generator that accepts an LVCMOS or crystal reference on its single input and delivers up to nine LVCMOS clock outputs, each programmable through the on-chip dividers. The PLL includes a bypass mode, which lets the reference clock pass through unmodified when jitter performance or a clean system clock is the priority. Maximum output frequency reaches 230 MHz, covering common Ethernet, FPGA, and processor reference clock rates.

Supply and temperature — narrow rail, industrial range

Package and footprint — 24-TSSOP on 0.65 mm pitch

The 4.40 mm body width keeps the footprint compact.

Frequently asked questions

Does CDCE949PWRG4 support LVCMOS output?

Yes, the CDCE949PWRG4 outputs LVCMOS levels on all nine outputs. The input side also accepts LVCMOS or a crystal reference. There is no differential I/O on this part.

What voltage does CDCE949PWRG4 require?

A regulated 1.8 V rail is the typical operating point. Do not connect to a 3.3 V or 2.5 V supply without a local regulator.

Can CDCE949PWRG4 replace CDCE949PWR?

The CDCE949PWRG4 shares the same base product number CDCE949 and the same 24-TSSOP package and pinout as the CDCE949PWR. The suffix difference indicates packaging or environmental compliance variant. Confirm the specific suffix requirements for your BOM before substituting.
