What this clock generator does on a P10xx/P20xx board
The Renesas 6V49205BPAGI is a PLL-based clock generator built specifically for Freescale P10xx and P20xx processors. It takes a single crystal input and fans it out to 19 clock outputs, with a maximum output frequency of 125 MHz. The input is single-ended (crystal), and the outputs are differential — matching the clock input requirements of those Power Architecture SoCs. Supply range is 3.135 V to 3.465 V, and the part operates across -40°C to 85°C, so it fits industrial and telecom environments where the processor board lives in a controlled rack or outdoor cabinet.
Fanout and signal integrity — 1:19 ratio
A 1:19 input-to-output ratio means one crystal oscillator drives 19 clock loads. That saves board space and BOM cost by eliminating multiple oscillators or a separate fanout buffer. The differential outputs (No/Yes in the spec) keep signal integrity clean over the traces to the processor and peripherals — important when routing multiple 125 MHz clocks across a dense PCB.
Lifecycle and sourcing — still an active line item
The 6V49205BPAGI carries an active lifecycle status and is ROHS3 compliant.
