TEXAS INSTRUMENTS CDC924 133-MHz CLOCK SYNTHESIZER/DRIVER FOR PC MOTHERBOARDS WITH 3-STATE OUTPUTS handbook

The CDC924 is a clock synthesizer/driver for PC motherboards that supports Pentium III class motherboards. It uses a 14.318 MHz crystal input to generate multiple output frequencies. The CDC924 includes spread spectrum clocking (SSC) with 0.5% downspread for reduced electromagnetic interference (EMI) performance. It also features power management control terminals, low output skew and jitter for clock distribution, and supports 2.5 V and 3.3 V supplies. The CDC924 generates various clocks including CPU, PCI, APIC, and REF clock signals.
