CGS701ATV General Description
CGS701A is an off the shelf clock driver specifically designed for today's high speed designs. It provides low skew outputs which are produced at different frequencies from three fixed input references. The XTALIN input pin is designed to be driven from a 25 MHz±40 MHz crystal oscillator.
The PLL, using a charge pump and an internal loop filter, multiplies this input frequency to create a maximum output frequency of four times the input.
The device includes a TRI-STATE® control pin to disable the outputs. This feature allows for low frequency functional testing and debugging.
Also included, is an EXTSEL pin to allow testing the chip via an external source. The EXTSEL pin, once set to high, causes the External-ClockMUX to change its input from the output of the VCO and Counter to the external clock signal provided via SKWTST input pin. (continued)
