General Description
The SCG2500AG5 is a mixed-signal phase lock loop
generating CMOS outputs from an intrinsically low jitter
voltage controlled crystal oscillator. The SCG2500AG5 is
based on Connor-Winfield’s SCG2500 series product line.
The SCG2500AG5 can lock to one of two possible
reference inputs at 8 kHz that are selectable using one
input select pin. The SCG2500AG5 has an improved filter
compared to the SCG2500. The new filter allows the
SCG2500AG5 to more closely track the selected input
reference and lowers switching MTIEs.
The SCG2500AG5 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. In the event of a LOL condition, the LOL
alarm will activate in 1us of the next rising edge of the
internal, 8 kHz reference. Switching references within 100
ns will then comply with GR-253-CORE requirements.
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 6 for more operational details.
The reference output at 8 kHz is derived from the
oscillator output. Note that the offset between the filtered
output and the reference input will change with each
reference rearrangement.
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.
This product is ROHS-5 compliant. ROHS-5 indicates
that this product is ROHS compliant except for lead from
those manufacturers wishing to take the lead exemption.
