SFX800G Data Sheet #: SG162 Page 2 of 8 Rev: 02 Date: 09/17/10 © Copyright 2010 The Connor-Winfield Corp. All Rights Reserved Specifications subject to change without notice The SFX-800G is a high precision frequency translator that translates one input, greater than 1MHz, to one of eight selectable output frequencies between 10 MHz and 1 GHz. The SFX-800G supports all major FEC rates such as 15/14, 255/237 etc. SFX-800G 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-800G provides a Functional Block Diagram Figure 1 jitter filtered, wander following output signal synchronized to a superior Stratum or peer input reference signal. The SFX-800G includes a lock detect (LD) alarm output and a loss of reference (LOR) alarm output. The LVPECL outputs may be disabled for external testing purposes by asserting a high signal to the Enable/Disable pin. The SFX-800G 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.

It is AC coupled and loaded with a 180 Ω resistor to ground. 3.0: VCO calibration occurs with each power-up and with each new output frequency selection. See figure 3 for the proper calibration sequence. Without a proper VCO calibration sequence, the unit will not lock and the output frequency could vary substantially from nominal.
