230 MHz PLL synthesizer with 1:5 fanout
The Texas Instruments CDCEL925PWRG4 is a PLL-based clock/frequency synthesizer that takes a single LVCMOS or crystal input and generates five LVCMOS outputs, each programmable up to 230 MHz. The integrated PLL includes a bypass mode, letting you feed through a reference clock when the synthesizer is not needed — useful for test modes or low-power standby.
The supply range is 1.7V to 1.9V, which means the board's 1.8V rail must stay within 5% regulation. A droop below 1.7V will cause the PLL to lose lock; a spike above 1.9V stresses the internal charge pump. If your system uses a 1.8V LDO, check its accuracy over load and temperature — a ±3% regulator leaves only 20 mV of margin on the low side.
Industrial temperature range and 16-TSSOP package
The 16-TSSOP package (4.40 mm wide) is a fine-pitch SOIC variant — it reflows with standard lead-free profiles and can be hand-soldered with a fine tip if you are doing a field repair. No differential outputs here: all five outputs are single-ended LVCMOS, so keep the trace lengths matched if you are driving multiple loads with tight skew requirements.
For production BOMs, this means standard lead times and no forced redesign cycle.
