cdc318a is a clock buffer produced by texas instruments. it supports 100mhz clock frequency and can output 18 clock signals at the same time.
The CDC318A is a high-performance clock buffer designed to distribute high-speed clocks in PC applications. It distributes one input to 18 outputs with minimum skew, operating from a 3.3-V power supply. The device is characterized for operation from 0°C to 70°C and is packaged in a 48-pin Shrink Small Outline (DL) package.
The device features a standard mode I2C serial interface for device control, allowing individual enable control for each output via three 8-bit registers. It supports up to four unbuffered SDRAM Dual Inline Memory Modules (DIMMs) and offers ESD protection exceeding 2000 V per MIL-STD-883, Method 3015.
