PRELIMINARY

VCXO JITTER ATTENUATOR &

FEMTOCLOCK™ MULTIPLIER

ICS814252I-02

ENERAL

ESCRIPTION

The ICS814252I-02 is a member of the

HiperClockS™ family of high performance clock

HiPerClockS™

solutions from IDT. The ICS814252I-02 is a PLL

based synchronous multiplier that is optimized for

PDH or SONET to Ethernet clock jitter attenuation

and frequency translation. The device contains two internal

frequency multiplication stages that are cascaded in series.

The first stage is a VCXO PLL that is optimized to provide

reference clock jitter attenuation. The second stage is a

FemtoClock™ frequency multiplier that provides the low jitter,

high frequency Ethernet output clock that easily meets Gigabit

and 10 Gigabit Ethernet jitter requirements. Pre-divider and

output divider multiplication ratios are selected using device

selection control pins. The multiplication ratios are optimized

to support most common clock rates used in PDH, SONET

and Ethernet applications. The VCXO requires the use of an

external, inexpensive pullable crystal. The VCXO uses external

passive loop filter components which allows configuration of

the PLL loop bandwidth and damping characteristics. The

device is packaged in a space-saving 32-VFQFN package and

supports industrial temperature range.

EATURES

•

Two LVDS outputs

Each output supports independent frequency selection at

25MHz, 125MHz, 156.25MHz and 312.5MHz

•

Two differential inputs support the following input types:

LVPECL, LVDS, LVHSTL, SSTL, HCSL

•

Accepts input frequencies from 8kHz to 155.52MHz including

8kHz, 1.544MHz, 2.048MHz, 19.44MHz, 25MHz, 77.76MHz,

125MHz and 155.52MHz

•

Attenuates the phase jitter of the input clock by using a low-

cost pullable fundamental mode VCXO crystal

•

VCXO PLL bandwidth can be optimized for jitter attenuation

and reference tracking

using external loop filter connection
