CDC925DL Description

Short technical summary and product information.

The Texas Instruments CDC925DL is a versatile clock synthesizer and driver engineered for PC motherboard applications, specifically supporting Pentium III class systems. It generates multiple system clocks from a single 14.318-MHz crystal input, including CPU, PCI, and other essential clock signals.

 

Key electrical specifications include a maximum frequency of 133 MHz, operating voltages ranging from 2.375V to 3.465V, and low output skew and jitter for reliable clock distribution. The device incorporates Spread Spectrum Clocking (SSC) for reduced EMI performance and features power management control terminals. It offers various clock outputs such as 4 CPU clocks (2.5 V, 100/133 MHz), 7 PCI clocks (3.3 V, 33.3 MHz), and others.

 

The CDC925DL is packaged in a 56-pin SSOP (Shrink Small Outline Package) with a surface mount type. Its operating temperature range is 0°C to 85°C. The device is designed for integration with clock generators like TI's Direct Rambus Clock Generators.
