Functional Description
The CY2305C and CY2309C are die replacement parts for
CY2305 and CY2309.
The CY2309C is a low-cost 3.3 V zero delay buffer designed to
distribute high speed clocks and is available in a 16-pin SOIC or
TSSOP package. The CY2305C is an 8-pin version of the
CY2309C. It accepts one reference input and drives out five low
skew clocks. The -1H versions of each device operate up to
100–133 MHz frequencies and have higher drive than the -1
devices. All parts have on-chip phase locked loops (PLLs) which
lock to an input clock on the REF pin. The PLL feedback is
on-chip and is obtained from the CLKOUT pad.
The CY2309C has two banks of four outputs each that are
controlled by the select inputs as shown in the Select Input
Decoding for CY2309C on page 5. If all output clocks are not
required, Bank B is three-stated. The input clock is directly
applied to the outputs by the select inputs for chip and system
testing purposes.
The CY2305C and CY2309C PLLs enter a power down mode
when there are no rising edges on the REF input. In this state,
the outputs are three-stated and the PLL is turned off. This
results in less than 12.0 A of current draw for commercial
temperature devices and 25.0 A for industrial and automotive-A
temperature parts. The CY2309C PLL shuts down in one
additional case as shown in the Select Input Decoding for
CY2309C on page 5.
In the special case when S2:S1 is 1:0, the PLL is bypassed and
REF is output from DC to the maximum allowable frequency. The
part behaves as a non-zero delay buffer in this mode and the
outputs are not three-stated.
The CY2305C or CY2309C is available in two or three different
configurations as shown in the Ordering Information on page 11.
The CY2305C-1 or CY2309C-1 is the base part. The CY2305-1H
or CY2309-1H is the high drive version of the -1. Its rise and fall
times are much faster than the -1.

Zero Delay and Skew Control
All outputs must be uniformly loaded to achieve Zero Delay
between the input and output. Since the CLKOUT pin is the
internal feedback to the PLL, its relative loading can adjust the
input or output delay.
For applications requiring zero input or output delay, all outputs
including CLKOUT are equally loaded. Even if CLKOUT is not
used, it must have a capacitive load equal to that on other
outputs for obtaining zero input or output delay.
For zero output to output skew, all outputs must be loaded
equally.
