SC464 - Motherboard Clock

Datasheet Summary

Description

OSCin, OSCout - These pins form an on-chip reference oscillator when connected to terminals of an external parallel resonant crystal (nominally 14.318 MHz).

OSCin may also serve as an input for an externally generated reference signal.

S0, S1, and S2 - Standard frequency select inputs.
