ENERAL
D
ESCRIPTION
The ICS813322-02 is a member of the
IC
S
HiperClockS™ family of high performance clock
HiPerClockS™
solutions from IDT. The ICS813322-02 is a PLL
based synchronous multiplier that is optimized for
Ethernet or SONET-to-SONET clock jitter atten-
uation 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 SONET output clock that meets up to SONET
OC-48 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 Ether net and SONET
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.

Two differential LVPECL outputs
Each output supports independent frequency selection at
19.44MHz, 77.76MHz, 155.52MHz and 622.08MHz
Two differential inputs support the following input types:
LVPECL, LVDS, HCSL
Accepts input frequencies from 8kHz to 156.25MHz including
8kHz,19.44MHz, 25MHz, 62.5MHZ, 77.76MHz, 125MHz,
155.52MHz and 156.25MHz
Each output has independently controlled dividers for
common SONET clock rates
Attenuates the phase jitter of the input clock by using a low-
cost pullable funamental mode VCXO crystal
VCXO PLL bandwidth can be optimized for jitter attenuation
and reference tracking
using external loop filter connection
FemtoClock frequency multiplier provides low jitter, high
frequency output
Absolute pull range: 50ppm
FemtoClock VCO frequency: 622.08MHz
RMS phase jitter @ 155.52MHz, using a 19.44MHz crystal
(12kHz – 20MHz): 1.16ps (typical)
