Multiplication

3 Description

The CDCS504-Q1 device is a LVCMOS input clock

buffer with selectable frequency multiplication.

The CDCS504-Q1 has an output enable pin.

The device accepts a 3.3-V LVCMOS signal at the

input.

The input signal is processed by a phased-locked

loop (PLL), whose output frequency is either equal to

the input frequency or multiplied by the factor of four.

By this, the device can generate output frequencies

between 2 MHz and 108 MHz.

A separate control pin can be used to enable or

disable the output. The CDCS504-Q1 device

operates in a 3.3-V environment.

It is characterized for operation from –40°C to 105°C

and is available in an 8-pin TSSOP package.
