IDT5V2305
FEATURES:
• High performance 1:5 clock driver for general purpose applica-
tions
• Operates up to 170MHz at VDD = 2.5V
• Operates up to 200MHz at VDD = 3.3V
• Pin-to-pin skew < 50ps
• VDD range: 2.3V to 3.6V
• Output enable glitch suppression
• 25Ω on-chip series dampening resistors
• Available in TSSOP and VFQFPN packages
DESCRIPTION:
The IDT5V2305 is a high performance, low skew clock buffer that
operates up to 200MHz. One bank of five outputs provides low skew copies
of CLK. Through the use of control pin G, the outputs of bank Y(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.
The IDT5V2305 is characterized for operation from -40°C to +85°C.
