CRYSTAL CONTROLLED OSCILLATORS

The Connor-Winfield

FPLA544 is a fixed frequency,

surface mount Crystal

Controlled Oscillator (XO)

designed for applications

requiring low jitter and a

±20ppm overall stability.

Operating at 3.3V supply

voltage, the FPLA544

provides LVPECL Differential

Outputs with enable/disable

function.

RECOMMENDATIONS

TABLE 6.0

Solder Reflow

The component solder used internal to this device has a melting point of

221

°C. The peak temperature inside the device should be less than or equal

to 220

°C for a maximum of 10 seconds

Wash

Ultrasonic cleaning is not recommended.

Notes

1)

Includes initial tolerance, deviation over temperat ure, supply and load variations, shock, vibration and 10 years

aging.

2)

When the oscillator is disabled, t he true output is in a low state (Vol) and the complementary output is in the high

state (VoH).

3)

Output must be terminated into 50 ohms to Vcc – 2V or Thevenin equivalent.

4)

Duty Cycle measured at 1.977V

PACKAGE CHARACTERISTICS

Package

Non-hermetic package consisting of an FR4 subs trate with grounded metal

cover.
