CDC318ADLR Description

Short technical summary and product information.

The Texas Instruments CDC318ADLR is a high-speed, low-skew 1-to-18 clock buffer designed for synchronous DRAM (SDRAM) clock buffering applications. It distributes one input clock signal to 18 outputs with minimal skew, making it suitable for PC applications.

 

This device operates from a 3.3V power supply and is characterized for operation from 0°C to 70°C. Key electrical specifications include an output skew of less than 250 ps and a pulse skew of less than 500 ps. It supports up to four unbuffered SDRAM Dual Inline Memory Modules (DIMMs).

 

The CDC318ADLR features an I2C serial interface for device control, providing individual enable control for each output. It operates at frequencies up to 100 MHz and includes ESD protection exceeding 2000V per MIL-STD-883, Method 3015. The device is packaged in a 48-pin Shrink Small Outline (SSOP) package.

 

Designed with optimized EMI performance in mind, the CDC318ADLR can reduce the need for damping resistors in many application layouts. The I2C inputs (SDATA and SCLOCK) are 5V tolerant and include integrated pull-up resistors.
