The CDC319 is a high-performance clock buffer that distributes one input (A) to 10 outputs (Y) with minimum skew for clock distribution. The CDC319 operates from a 3.3-V power supply, and is characterized for operation from 0°C to 70°C.

The device provides a standard mode (100K-bits/s) I2C serial interface for device control. The implementation is as a slave/receiver. The device address is specified in the I2C device address table. Both of the I2C inputs (SDATA and SCLOCK) provide integrated pullup resistors (typically 140 k) and are 5-V tolerant.

Three 8-bit I2C registers provide individual enable control for each of the outputs. All outputs default to enabled at powerup. Each output can be placed in a disabled mode with a low-level output when a low-level control bit is written to the control register. The registers are write only and must be accessed in sequential order (i.e., random access of the registers is not supported).Read more
