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 < 50ps

• 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.

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.
