Data Sheet #: SG144 Page 2 of 8 Rev: 00 Date: 6/6/08 © Copyright 2008 The Connor-Winfield Corp. All Rights Reserved Specifications subject to change without notice The SFX-400G is a high precision frequency translator that translates one of two inputs, greater than 1MHz, to one of four selectable output frequencies between 10 MHz and 945 MHz. The SFX-400G supports all major FEC rates such as 15/14, 255/237 etc. SFX-400G 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-400G provides a jitter filtered, wander following output signal synchronized to Functional Block Diagram Figure 1 a superior Stratum or peer input reference signal. The SFX-400G includes a lock detect alarm output. The PLL control voltage is brought out through a 470 kΩ resistor and can be used to determine when the pull range limits are reached. The LVPECL outputs may be disabled for external testing purposes by asserting a high signal to the Enable/ Disable pin. The SFX-400G package typical dimensions are 1.2" x 1.0" x 0.285". Parts are assembled using high temperature solder to withstand surface mount reflow process.
