CY2305C  
CY2309C  
PRELIMINARY  
3.3V Zero Delay Clock Buffer  
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 PLLs which lock to an input clock  
on the REF pin. The PLL feedback is on-chip and is obtained  
from the CLKOUT pad.  
Features  
10 MHz to 100-133 MHz operating range, compatiblewith CPU  
and PCI bus frequencies  
Zero input and output propagation delay  
Multiple low skew outputs  
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 3. If all output clocks are not  
required, BankB is three-stated. The input clock is directly  
applied to the outputs by the select inputs for chip and system  
testing purposes.  
One input drives five outputs (CY2305C)  
One input drives nine outputs, grouped as 4 + 4 + 1 (CY2309C)  
50 ps typical cycle-cycle jitter (15 pF, 66 MHz)  
Test Mode to bypass phase locked loop (PLL) (CY2309C) only,  
see “Select Input Decoding for CY2309C” on page 3  
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 μA of current draw for commercial  
temperature devices and 25.0 μA for industrial temperature  
parts. The CY2309C PLL shuts down in one additional case as  
shown in the “Select Input Decoding for CY2309C” on page 3.  
Available in space saving 16-pin 150 Mil SOIC or 4.4 mm  
TSSOP packages (CY2309C), and 8-pin, 150 Mil SOIC  
package (CY2305C)  
3.3V operation  
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 like a non-zero delay buffer in this mode and the  
outputs are not three-stated.  
Industrial temperature available  
Functional Description  
The CY2305C and CY2309C are die replacement parts for  
CY2305 and CY2309.  
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 -1s.  
The CY2309C 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 CY2305C is an 8-pin version of the
