What technical benefits does this product series offer?
This series of crystal oscillator offers:
What are the construction characteristics of this product series?
This product series consists of a single CMOS ASIC and a fundamental mode BAW quartz crystal packaged
inside a hermetically sealed ceramic leadless SMD package. The leadless SMD package has four gold plated
contact I/O pads. The package has a seam sealed metal cover that is case grounded for improved EMI
performance.
What is the input supply voltage for this product series?
The nominal supply voltage and tolerance is provided on the datasheet.
What are the input current specifications for this product series?
The input current specification is listed in milliamps as a maximum value and is provided on the datasheet.
What are the frequency stability and operating temperature range options for this product series?
The available operating temperature range and frequency stability options can be found on the datasheet.
Does this series offer a tri-state output function?
This product series offers a tri-state output function to facilitate the customer's use of in-process assembly testing
or for the use of multiple clocks on the same node. It features a tri-state output control on pad one (1) where the
output is three-stated (tri-state condition) when the voltage at the control pad (pad 1) is set to a logic low state. In
this condition (see the figure below), the internal oscillator circuit continues to operate and the output pad is
placed into a high impedance state. If the voltage at the control pad is set to no connect or a logic high state, the
output is enabled (clocking).
Note: The oscillator has an internal pull up resistor on the control pad. The series datasheet provides the V
