CRYSTAL CONTROLLED OSCILLATORS

The Connor-Winfield TFLD546E2

is a Surface Mount Temperature

Compensated Crystal Oscillator

(TCXO). Operating at 3.3Vdc,

the TFLD546E2 will maintain

±4.6ppm frequency tolerance

over 20 years. The TFLD546E2

is offered in a surface mount

package for automated

assembly.

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.

Note:

1) Inclusive of calibration, frequency vs. temper ature stability, supply voltage change, load

change, shock and vibration, 20 years aging.

2) Oscillator output is enabled with no co nnection on pad 2. Output is at hig h impedance when

disabled.
