CY2304  
3.3V Zero Delay Buffer  
The part has an on-chip phase-locked loop (PLL) that locks to  
an input clock presented on the REF pin. The PLL feedback is  
required to be driven into the FBK pin, and can be obtained  
from one of the outputs. The input-to-output skew is  
guaranteed to be less than 250 ps, and output-to-output skew  
is guaranteed to be less than 200 ps.  
Features  
• Zero input-output propagation delay, adjustable by  
capacitive load on FBK input  
• Multiple configurations – see “Available Configura-  
tions” table  
The CY2304 has two banks of two outputs each.  
• Multiple low-skew outputs  
The CY2304 PLL enters a power-down state when there are  
no rising edges on the REF input. In this mode, all outputs are  
three-stated and the PLL is turned off, resulting in less than  
25 µA of current draw.  
— Output-output skew less than 200 ps  
— Device-device skew less than 500 ps  
• 10-MHz to 133-MHz operating range  
• Low jitter, less than 200 ps cycle-cycle  
• Space-saving 8-pin 150-mil SOIC package  
• 3.3V operation  
Multiple CY2304 devices can accept the same input clock and  
distribute it in a system. In this case, the skew between the  
outputs of two devices is guaranteed to be less than 500 ps.  
The CY2304 is available in two different configurations, as  
shown in the Available Configurationstable. The CY23041  
is the base part, where the output frequencies equal the  
reference if there is no counter in the feedback path.  
• Industrial temperature available  
Functional Description  
The CY2304 is a 3.3V zero delay buffer designed to distribute  
high-speed clocks in PC, workstation, datacom, telecom, and  
other high-performance applications.  
The CY23042 allows the user to obtain Ref and 1/2x or 2x  
frequencies on each output bank. The exact configuration and  
output frequencies depends on which output drives the  
feedback pin.
