CY2V995  
2.5/3.3V 200-MHz Multi-Output  
Zero Delay Buffer  
Description  
Features  
• 2.5V or 3.3V operation  
The CY2V995 is a low-voltage, low-power, eight output,  
200-MHz clock driver. It features function necessary to  
optimize the timing of high-performance computer and  
communication systems.  
The user can program the frequency of the output banks  
through nF[0:1] and DS[0:1] pins. Any one of the outputs can  
be connected to feedback input to achieve different reference  
frequency multiplication and divide ratios and zero  
input-output delay.  
The device also features split output bank power supplies  
which enable the user to run two banks (1Qn and 2Qn) at a  
power supply level different from that of the other two banks  
(3Qn and 4Qn). Additionally, the PE pin controls the synchro-  
nization of the output signals to either the rising or the falling  
edge of the reference clock.  
• Split output bank power supplies  
• Output frequency range: 6 MHz to 200 MHz  
• Output-output skew: < 150 ps  
• Cycle-cycle jitter: < 100 ps  
• Selectable positive or negative edge synchronization  
8 LVTTL outputs driving 50terminated lines  
• LVCMOS/LVTTL over-voltage tolerant reference input  
• Selectable phase-locked loop (PLL) frequency range  
and lock indicator  
• (1-6,8,10,12)x multiply and (1/2,1/4)x divide ratios  
• Spread-Spectrum-compatible  
• Power-down mode  
• Industrial temperature range: –40°C to +85°C  
• 44-pin TQFP package
