CRYSTAL CONTROLLED OSCILLATORS

The Connor-Winfield

FPHA554 is a fixed frequency

surface mount Crystal

Controlled Oscillator (XO)

designed for applications

requiring low jitter and tight

frequency stability. Operating

at 5.0V supply voltage, the

FPHA554 provides PECL

Differential Outputs with an

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.

Notes

1)

Includes initial tolerance, deviation over t emperature, supply and load variations, shock, vibrati on and 10 years aging.

2)

When the oscillator is disabled, the true output is in a low state (Vol) and the complementary output is in the high s tate (VoH).

3)

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

4)

Duty Cycle measured at 3.67V

PACKAGE CHARACTERISTICS

TABLE 5.0

Package

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

cover.
