QT89 SERIES

HIGH-RELIABILITY MINIATURE CLOCK OSCILLATORS

1.8 to 5.0Vdc - 15kHz to 160MHz

Q-TECH

CORPORATION

QT89 (Revision J, January 2011) (ECO #10087)

Description

Q-Tech’s surface-mount QT89 oscillators consist of an IC 5Vdc,

3.3Vdc, 2.5Vdc, 1.8Vdc clock square wave generator and a

round AT high-precision quartz crystal built in a rugged leaded

miniature package. This package is primarily designed for

down-hole applications with 5Vdc or 3.3Vdc supply voltage.

Do not apply soldering heat on oscillator package since it could damage the unit. Hand soldering is recommended. Wave solder at 245ºC for 15s max. Thermal Characteristics The heat transfer model in a hybrid package is described in figure 1.

QT89 SERIES HIGH-RELIABILITY MINIATURE CLOCK OSCILLATORS 1.8 to 5.0Vdc - 15kHz to 160MHz Q-TECH CORPORATION Period Jitter As data rates increase, effects of jitter become critical with its budgets tighter. Jitter is the deviation of a timing event of a signal from its ideal position. Jitter is complex and is composed of both random and deterministic jitter components. Random jitter (RJ) is theoretically unbounded and Gaussian in distribution.
