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
Block Diagram
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
μ
A of current draw for commercial temper-
ature devices and 25.0
μ
A 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.
All outputs have less than 200 ps of cycle-cycle jitter. The input
to output propagation delay on both devices is guaranteed to
be less than 350 ps, and the output to output skew is
guaranteed to be less than 250 ps.
The CY2305/CY2309 is available in two/three different config-
urations, 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.
