description  
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.  
2
The device provides a standard mode (100K-bits/s) I C serial interface for device control. The implementation  
2
2
is as a slave/receiver. The device address is specified in the I C device address table. Both of the I C inputs  
(SDATA and SCLOCK) provide integrated pullup resistors (typically 140 kΩ) and are 5-V tolerant.  
2
Three 8-bit I C 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).  
The CDC319 provides 3-state outputs for testing and debugging purposes. The outputs can be placed in a  
high-impedance state via the output-enable (OE) input. When OE is high, all outputs are in the operational state.  
When OE is low, the outputs are placed in a high-impedance state. OE provides an integrated pullup resistor.
