Texas Instruments High-Performance Analog Application Specific Clock/Timing CDC924DLG4

The CDC924 is a clock synthesizer and driver designed for use in Intel Pentium III class motherboards. It operates with a 14.318 MHz crystal input to generate multiple output frequencies, including 100 MHz and 133 MHz for CPU, 33.3 MHz for PCI, and various other clock signals. The device features spread spectrum clocking (SSC) with a 0.5% downspread to reduce electromagnetic interference (EMI). It supports both 2.5 V and 3.3 V power supplies and includes power management control terminals for efficient operation. The CDC924 provides low output skew and jitter, ensuring reliable clock distribution. It is packaged in a 56-pin SSOP format and is compatible with TI's Direct Rambus clock generators. The outputs are 3-state capable, allowing for flexible integration into various systems.
