The TLC2933AIPWR is a single-circuit Phase Lock Loop (PLL) IC from Texas Instruments, accepting CMOS inputs and delivering CMOS outputs. Its maximum operating frequency of 110 MHz targets clock generation, frequency synthesis, and clock recovery in systems that need a clean, locked clock from a reference. The supply voltage range of 2.85 V to 5.25 V lets it run from a 3.3 V or 5 V rail directly — no extra regulator needed. The 2:1 input-to-output ratio means two reference inputs feed one PLL output, useful for selecting between a primary and backup clock source. Operating temperature from -20°C to 75°C covers indoor telecom, office equipment, and industrial control cabinets, but not extended outdoor or under-hood automotive environments.
Parametric deep-dive: supply, frequency, and package
The 110 MHz ceiling is the key selection axis: if your VCO or reference clock runs above that, this part cannot lock. Below that, the wide supply tolerance simplifies rail design — the PLL's internal charge pump and phase detector work across the full 2.85 V to 5.25 V range without external level shifting. The 14-TSSOP package with 0.65 mm pitch is a common footprint for clock ICs. The input and output are both single-ended CMOS, so no differential routing is needed — keep the trace short to the load to avoid reflections at 110 MHz. No internal divider or multiplier on the output — the loop feedback path sets the multiplication factor externally. The divider/multiplier is a Yes/No flag meaning the part has a divider on the feedback path but no output multiplier.
