2.5V TO 3.3V HIGH
PERFORMANCE CLOCK
BUFFER
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.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

G I Output Enable Control for Y(0:4) Outputs. This output enable is active HIGH. If this pin is Logic HIGH, the Y(0:4) clock outputs will follow the
input clock (CLK). If this pin is logic LOW, the Y(0:4) outputs will drive low independent of the state of CLK.
