PERFORMANCE CLOCK

BUFFER

DESCRIPTION:

The IDT5V2310 is a high performance, low skew clock buffer that

operates up to 200MHz. Two banks of five outputs each provide low skew

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.

The IDT5V2310 is characterized for operation from -40°C to +85°C.

PIN DESCRIPTION

TERMINAL

Symbol I/O Description

1G I Output Enable Control for 1Y(0:4) Outputs. This output enable is active HIGH. If this pin is Logic HIGH, the 1Y(0:4) clock outputs will follow the

input clock (CLK). If this pin is logic LOW, the 1Y(0:4) outputs will drive low independent of the state of CLK.

2G I Output Enable Control for 2Y(0:4) Outputs. This output enable is active HIGH. If this pin is Logic HIGH, the 2Y(0:4) clock outputs will follow the

input clock (CLK). If this pin is logic LOW, the 2Y(0:4) outputs will drive low independent of the state of CLK.

OUTPUT ENABLE GLITCH SUPPRESSION CIRCUIT

The purpose of the glitch suppression circuitry is to ensure the output enable sequence is synchronized with the clock input such that the output buffer will be

enabled on the next full period of the input clock (negative edge triggered by the input clock). The G input must be stable one tEN - time prior to the falling edge

of the CLK for predictable operation.
