CY2PD817  
320-MHz 1:7 PECL to PECL/CMOS Buffer  
Features  
Description  
• DC to 320-MHz operation  
• 50-ps output-output skew  
The CY2PD817 is a low-voltage LVPECL-to-LVPECL and  
LVCMOS fanout buffer designed for servers, data communi-  
cations, and clock management.  
• 30-ps cycle-cycle jitter  
The CY2PD817 is ideal for applications requiring mixed differ-  
ential and single-ended clock distribution. This device accepts  
an LVPECL input reference clock and provides one LVPECL  
and six LVCMOS/LVTTL output clocks. The outputs are parti-  
tioned into three banks of one, two, and four outputs. The  
LVPECL output is a buffered copy of the input clock while the  
LVCMOS outputs are divided by 1, 2, and 4. When CLRDIV is  
set HIGH, the output dividers are set to 1. In this mode, the  
maximum input frequency is limited to 250 MHz.  
• 2.5V power supply  
• LVPECL input @ 320-MHz Operation  
• One LVPECL output @ 320-MHz Operation  
• Four LVCMOS/LVTTL outputs @ 250 MHz/160 MHz  
• Two LVCMOS/LVTTL outputs @ 250 MHz/80 MHz  
• 45% to 55% output duty cycle  
• Output divider control  
• Output enable/disable control  
• Operating temperature range: 0°C to +85°C  
• 24-pin TSSOP  
When OE is set HIGH, the outputs are disabled in a High-Z  
state.
