CRYSTAL CONTROLLED OSCILLATORS

The Connor-Winfield

FPLD64BEX is a fixed

frequency, surface mount

Crystal Controlled Oscillator

(XO) designed for

applications requiring low

jitter and a ±20ppm frequency

stability. Operating at 3.3V

supply voltage, the

FPLD64BEX provides

LVPECL Differential Outputs

with Enable/Disable function.

PROCESS 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.

PACKAG E CHARACTERISTICS

TABLE 5.0

Package

Non-hermetic package consisting of an FR4 substrate with grounded metal

cover.

Notes

1)

Frequency stability vs. change in temperature.

2)

Inclusive of frequency calibration @ 25°C, frequency stability vs. change in temperature, supply and load variations,

shock and vibration and 15 years aging.

3)

When the oscillator is disabled, the true output and the complementary output are in the high impedance state.

4)

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

5)

Duty Cycle measured at 1.977V
