DIFFERENTIAL-TO-LVHSTL ZERO DELAY BUFFER

GENERAL DESCRIPTION

FEATURES

The ICS8725 is a high performance LVHSTL

• Fully integrated PLL

,&6

zero delay buffer and a member of the

• 5 LVHSTL outputs each with the ability to drive 50Ω to

ground

HiPerClockS™

HiPerClockS™ family of High Performance

Clocks Solutions from ICS. The VCO operates

at a frequency range of 250MHz to 500MHz.

• Voh (max) = 1.2V

Utilizing one of the outputs as feedback to the PLL output

frequencies up to 500MHz can be regenerated with zero

delay with respect to the input. Dual reference clock inputs

support redundant clock or multiple reference applications.

• 31.25MHz to 500MHz output frequency range

• Spread Smart™ for regenerating spread spectrum clocks

• Differential reference clock inputs accept any differential

input signal

•· Differential reference clock inputs will accept single ended

input signal with one of the inputs biased with a resistor

network

• 31.25MHz to 622MHz input frequency range

• LVCMOS / LVTTL control inputs

• 3.3V core, 1.8V output operating supply voltage

• 32 lead low-profile QFP (LQFP), 7mm x 7mm x 1.4mm

package body, 0.8mm package lead pitch

• 0°C to 70°C ambient operating temperature

• Industrial temperature version available upon request
