CDC319DB Description

Short technical summary and product information.

The Texas Instruments CDC319DB is a high-performance clock buffer that distributes one input signal to ten outputs with minimal skew, making it ideal for clock distribution in SDRAM applications. It operates from a 3.3V power supply and is characterized for operation from 0°C to 70°C. The device features an I2C serial interface for control, allowing individual enable control for each output. Outputs default to enabled at power-up and can be placed in a disabled mode or a high-impedance state via the output-enable (OE) input. The CDC319DB supports up to two unbuffered SDRAM DIMMs and is packaged in a 28-pin SSOP (Shrink Small Outline Package).

 

Key electrical characteristics include an input type of LVTTL and an output type of LVTTL/TTL, with a maximum frequency of 100 MHz. The output skew is less than 250 ps, and pulse skew is less than 500 ps. The device utilizes distributed VCC and ground pins to reduce switching noise and offers ESD protection exceeding 2000V per MIL-STD-883, Method 3015. The 28-SSOP package has a width of 5.30mm (0.209").
