CDC318ADLRG4 Description

Short technical summary and product information.

The Texas Instruments CDC318ADLRG4 is a high-performance clock buffer designed to distribute high-speed clocks in PC applications. This device distributes one input to 18 outputs with minimal skew, making it ideal for synchronous DRAM clock buffering. It operates from a 3.3-V power supply and is characterized for operation from 0°C to 70°C.

 

The CDC318ADLRG4 features LVTTL input and output types, with a maximum output skew of 250 ps and pulse skew of 500 ps. It supports up to four unbuffered SDRAM Dual Inline Memory Modules (DIMMs). The device operates at 100 MHz and includes an I2C serial interface for device control, providing individual enable control for each output. Distributed VCC and ground pins help reduce switching noise. ESD protection exceeds 2000 V per MIL-STD-883, Method 3015.

 

Packaged in a 48-pin Shrink Small Outline (SSOP) package, the CDC318ADLRG4 is designed for surface mount applications. The package dimensions are 48-SSOP, with a width of 7.50 mm. This clock buffer is suitable for applications requiring precise clock distribution with low skew.
