ICS813078BYI REV. A OCTOBER 6, 2008
General Description
The ICS813078I is a member of the HiperClocks
family of high performance clock solutions from IDT.
The ICS813078I a PLL based synchronous clock
solution that is optimized for wireless infrastructure
equipment where frequency translation and jitter
attenuation is needed.
The device contains two internal PLL stages that are cascaded in
series. The first PLL stage attenuates the reference clock jitter by
using an internal or external VCXO circuit. The internal VCXO
requires the connection of an external inexpensive pullable crystal
(XTAL) to the ICS813078I. This first PLL stage (VCXO PLL) uses
external passive loop filter components which are used to optimize
the PLL loop bandwidth and damping characteristics for the given
application. The output of the first stage VCXO PLL is a stable and
jitter-tolerant 30.72MHz reference input for the second PLL stage.
The second PLL stage provides frequency translation by
multiplying the output of the first stage up to 491.52MHz or
614.4MHz. The low phase noise characteristics of the VCXO-PLL
clock signal is maintained by the internal FemtoClockPLL, which
requires no external components or complex programming. Two
independently configurable frequency dividers translate the
internal VCO signal to the desired output frequencies. All
frequency translation ratios are set by device configuration pins.
Supported input reference clock frequencies:
10MHz, 12.8MHz, 15MHz, 15.36MHz, 20MHz, 30.72MHz,
61.44MHz, and 122.88MHz
Supported output clock frequencies:
30.72MHz, 38.4MHz, 61.44MHz, 76.8MHz, 122.88MHz,
153.6MHz, 245.76MHz, 491.52MHz, and 614.4MHz
Features
Nine outputs, organized in three independent output banks with
differential LVPECL and single-ended outputs
One differential input clock can accept the following differential
input levels: LVDS, LVPECL, LVHSTL
One single-ended clock input
Frequency generation optimized for wireless infrastructure
Attenuates the phase jitter of the input clock signal by using
low-cost pullable fundamental mode crystal (XTAL)
Internal Femtoclock frequency multiplier stage eliminates the
need for an expensive external high frequency VCXO
