The SCG2560 is based on Connor-Winfield’s SCG2500 series product line. The SCG2560 can lock to one of two possible reference inputs at 25 MHz that are selectable using one input select pin. The SCG2560 has an improved filter compared to the SCG2500. The new filter allows the SCG2560 to more closely track the selected input reference and lowers switching MTIEs. The SCG2560 provides 3 alarm outputs, Loss of Reference A, (LOR A) Loss of Reference B, (LOR B), and Loss of Lock, (LOL) as compared to the SCG2500’s combined alarms. LOL alarm is active when the phase error exceeds 1us. LOR A and LOR B independently monitor the input references. If Both references are lost the unit will go into Free Run automatically. When both references are lost, the unit should be forced into Free Run (pin 5 = 1). LOR A and LOR B can then be monitored until the references return. Refer to Table 5 for more operational details. The reference output at 25 MHz is derived from the oscillator output. Phase alignment of the reference output to the input cannot be guaranteed with dual input units. The package maximum dimensions are .780” x .830” x .350” on a six layer FR4 board with surface mount pins. Parts are assembled using high temperature solder to withstand surface mount reflow processes. Tri-State is not available with this model.
