CDC319DBR Description

Short technical summary and product information.

The Texas Instruments CDC319DBR is a high-speed, low-skew 1-to-10 clock buffer. It is designed to distribute a single clock input to ten outputs with minimal skew, making it suitable for SDRAM clock buffering applications. The device operates from a 3.3V power supply and features LVTTL input and output types.

 

Key features include an output skew of less than 250 ps and pulse skew of less than 500 ps. It supports up to two unbuffered SDRAM DIMMs. The CDC319DBR includes an I2C serial interface for device control, allowing individual enable control for each output. It also provides 3-state outputs for testing and debugging purposes via an output-enable (OE) input.

 

Packaged in a 28-pin SSOP, the CDC319DBR is surface-mountable. It is characterized for operation in the 0°C to 70°C temperature range. The distributed VCC and ground pins help reduce switching noise, and ESD protection exceeds 2000V per MIL-STD-883, Method 3015.
