Functional Specifications
Crystal Input
The CY2213 receives its reference from an external crystal.
Pin XIN is the reference crystal input, and pin XOUT is the
reference crystal feedback. The parameters for the crystal are
given on page 5 of this data sheet. The oscillator circuit
requires external capacitors. Please refer to the application
note entitled
Crystal Oscillator Topics
for details.
Select Input
There is only one select input, pin S. This pin selects the
frequency multiplier in the PLL, and is a standard LVCMOS
input. The S pin has an internal pull-up resistor. The multiplier
selection is given on page 2 of this data sheet.
PECL Clock Output Driver
Figure 5
and
Figure 6
show the clock output driver.
An alternative termination scheme can be used to drive a
standard PECL fanout buffer
