All Rights Reserved Specifications subject to change without notice 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 Functional Block Diagram Figure 1 Frequency Divider Filter PECL VCXO Frequency Divider Q QN Input Frequency Select A Select B Lock Detector Enable/Disable VCXO Monitor 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.
