SFX-102G Datasheet, PDF (2/8 Pages) Connor-Winfield Corporation – Synchronous Clock Generators

General Description
The SFX-102G provides high precision phase lock loop frequency
translation for the telecommunication applications. The SFX-102G
product generates LVPECL outputs from an intrinsically low jitter,
voltage controlled crystal oscillator.
SFX-102G is well suited for use in line cards, service termination
cards and similar functions to provide reliable reference, phase
locked, synchronization for TDM, PDH, SONET and SDH network
equipment. The SFX-102G provides a jitter filtered, wander
following output signal sychronized to a superior Stratum or peer
input reference signal.
The SFX-102G includes a lock detect alarm output. The PLL
control voltage is brought out through a 470 kΩ restistor and can
be used to determine when the pull range limits are reached.The
LVPECL outputs may be put into the tri-state high impedance
condition for external testing purposes by asserting a high signal
to the Enable/Disable pin.
The SFX-102G locks to any one of four pred-determined input
frequencies selected using the SELECT (A&B) lines (See Table
4). The output may be any single frequency from 77.76 MHz to
170 MHZ.
The SFX-102G is a 3.3 Volt component that will typically draw
75mA. The SFX-102G is designed to be used in applications
that require temperature rating of -40°C - 85° C. The SFX-102G
package typical dimensions are 1.0” x 0.80” x 0.285” (See fig. 2 for
maximum dimensions).
This product is ROHS compliant.
