The PLL (Yes) locks the output phase to the crystal reference, reducing jitter on the clock tree—critical for Rambus-style high-speed memory interfaces where timing margin is tight. The 1:2 ratio means one crystal input drives two clock outputs; each output is LVCMOS, so it interfaces directly with standard logic inputs without external level shifting. The dual-frequency capability (9.375 MHz main, 400 Hz secondary) suggests a design where a slow clock feeds a power-management or watchdog block while the faster clock drives the core logic.
Sourcing posture
It is Active and RoHS non-compliant. The 16-TSSOP package and 3.04 V to 3.56 V supply are common, so a functional equivalent search should focus on PLL-equipped clock generators in the same footprint and voltage range.
