General Description

Features

The SCG2560G5 is a mixed-signal phase lock loop

generating CMOS outputs from an intrinsically low jitter

voltage controlled crystal oscillator. The SCG2560G5 is

based on Connor-Winfield’s SCG2500 series product line.

The SCG2560G5 can lock to one of two possible

reference inputs at 25 MHz that are selectable using one

input select pin. The SCG2560G5 has an improved filter

compared to the SCG2500. The new filter allows the

SCG2560G5 to more closely track the selected input

reference and lowers switching MTIEs.

• Commercial Temperature Range

(0°- 70°C)

• Phase Locked Output Frequency

• Intrinsically Low Jitter Crystal

• Two Selectable References @ 25

MHz

The SCG2560G5 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.

• Hitless Reference Switching

• 2 Independent Reference Monitors

• LOL Alarm Output

• Force Free Run Function

• Automatic Free Run Operation upon

loss of both references

• Input Duty Cycle Tolerant

• 3.3 Volt Power Supply

• Small Size: 0.78” x 0.83” x 0.35”

• Surface Mount, DIL Package

• ROHS-5 compliant

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.
