FEATURES:
DESCRIPTION:
• High performance 1:10 clock driver for general purpose
applications
• 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
Ω on-chip series dampening resistors
• 25Ω
• Available in TSSOP and VFQFPN packages
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.

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.

Description
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.
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.
