CY2308  
3.3V Zero Delay Buffer  
Input Decoding.” If all output clocks are not required, Bank B  
can be three-stated. The select inputs also allow the input  
clock to be directly applied to the output for chip and system  
testing purposes.  
Features  
• Zero input-output propagation delay, adjustable by  
capacitive load on FBK input  
• Multiple configurations, see “Available CY2308  
Configurations” table  
• Multiple low-skew outputs  
The CY2308 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  
50 µA of current draw. The PLL shuts down in two additional  
cases as shown in the “Select Input Decoding” table.  
Multiple CY2308 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 700 ps.  
• Twobanksoffouroutputs,three-stateablebytwoselect  
inputs  
• 10-MHz to 133-MHz operating range  
• 75ps typical cycle-to-cycle jitter (15pF, 66MHz)  
The CY2308 is available in five different configurations, as  
shown in the “Available CY2308 Configurations” table on page  
2. The CY2308–1 is the base part, where the output  
frequencies equal the reference if there is no counter in the  
feedback path. The CY2308–1H is the high-drive version of  
the –1, and rise and fall times on this device are much faster.  
The CY2308–2 allows the user to obtain 2X and 1X  
frequencies on each output bank. The exact configuration and  
output frequencies depends on which output drives the  
feedback pin. The CY2308–3 allows the user to obtain 4X and  
2X frequencies on the outputs.  
• Space-saving 16-pin 150-mil SOIC package or 16-pin  
TSSOP  
• 3.3V operation  
• Industrial Temperature available  
Functional Description  
The CY2308 is a 3.3V Zero Delay Buffer designed to distribute  
high-speed clocks in PC, workstation, datacom, telecom, and  
other high-performance applications.  
The part has an on-chip PLL which 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 350 ps, and output-to-output skew is guaranteed to be  
less than 200 ps.  
The CY2308–4 enables the user to obtain 2X clocks on all  
outputs. Thus, the part is extremely versatile, and can be used  
in a variety of applications.  
The CY2308–5H is a high-drive version with REF/2 on both  
banks.  
The CY2308 has two banks of four outputs each, which can  
be controlled by the Select inputs as shown in the table “Select  
Pin Configuration
