IDT5V2310  
2.5V TO 3.3V HIGH  
PERFORMANCE CLOCK  
BUFFER  
FEATURES:  
DESCRIPTION:  
• High performance 1:10 clock driver for general purpose  
applications  
The IDT5V2310 is a high performance, low skew clock buffer that  
operatesupto200MHz. Twobanksoffiveoutputseachprovidelowskew  
copies of CLK. Through the use of control pins 1G and 2G, the outputs of  
banks 1Y(0:4) and 2Y(0:4) can be placed in a low state regardless of CLK  
input. The device operates in 2.5V and 3.3V environments. The built-in  
output enable glitch suppression ensures a synchronized output enable  
sequence to distribute full period clock signals.  
• Operates up to 200MHz at VDD = 3.3V  
• Pin-to-pin skew < 100ps  
• VDD range: 2.3V to 3.6V  
• Output enable glitch suppression  
• Distributes one clock input to two banks of five outputs  
• 25Ω on-chip series dampening resistors  
• Available in TSSOP and VFQFPN packages  
The IDT5V2310 is characterized for operation from -40°C to +85°C.
