Functional Description
The CY2309 is a low-cost 3.3V zero delay buffer designed to
distribute high-speed clocks and is available in a 16-pin SOIC
or TSSOP package. The CY2305 is an 8-pin version of the
CY2309. It accepts one reference input, and drives out five
low-skew clocks. The -1H versions of each device operate at
up to 100-/133-MHz frequencies, and have higher drive than
the -1 devices. All parts have on-chip 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 CY2309 has two banks of four outputs each, which can
be controlled by the Select inputs as shown in the “Select Input
Decoding” table on page 2. If all output clocks are not required,
BankB can be three-stated. The select inputs also allow the
input clock to be directly applied to the outputs for chip and
system testing purposes.
The CY2305 and CY2309 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, resulting
in less than 12.0 µA of current draw for commercial temperature devices and 25.0 µA for industrial temperature parts. The
CY2309 PLL shuts down in one additional case as shown in
the table below.
Multiple CY2305 and CY2309 devices can accept the same
input clock and distribute it. In this case, the skew between the
outputs of two devices is guaranteed to be less than 700 ps.
The CY2305/CY2309 is available in two/three different configurations, as shown in the ordering information (page 10). The
CY2305-1/CY2309-1 is the base part. The CY2305-1H/
CY2309-1H is the high-drive version of the -1, and its rise and
fall times are much faster than the -1s.

REF. Input to CLKA/CLKB Delay vs. Loading Difference between CLKOUT and CLKA/CLKB Pins
Zero Delay and Skew Control
All outputs should 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-output delay. This is shown in the above graph.
other outputs, for obtaining zero input-output delay. If input to
output delay adjustments are required, use the above graph to
calculate loading differences between the CLKOUT pin and
other outputs.
For applications requiring zero input-output delay, all outputs,
including CLKOUT, must be equally loaded. Even if CLKOUT
is not used, it must have a capacitive load, equal to that on
For zero output-output skew, be sure to load all outputs
equally. For further information refer to the application note
entitled “CY2305 and CY2309 as PCI and SDRAM Buffers.”
