Description
The VS-500 is a SAW based voltage controlled oscillator that
operates at the fundamental frequency of the internal SAW
filter. This resonator is a high Q quartz device that enables
the circuit to achieve low phase jitter performance over a wide
operating temperature range. The oscillator is housed in a
hermetically sealed J-lead surface mount package offered on
tape and reel. It has an output disable to facilitate on-board
testing.

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation
is not implied at these or any other conditions in excess of conditions represented in the operational sections of
this datasheet. Exposure to absolute maximum ratings for extended periods may adversely affect device
reliability.

LV-PECL to LV-PECL: For short transmission lengths, the power
consumption could be reduced by removing the 100Ω resistor and
doubling the value of the pull down resistors.
LV-PECL to LVDS: Restricted for short transmission lengths.
Configuration may require modification depending on LVDS receiver.

Functional Test: Allows standard power supply configuration.
Since AC coupled, the LV-PECL levels cannot be measured.
Production Test: Allows direct DC coupling into 50Ω measurement
equipment. Must bias the power supplies as shown. Similar to Figure 1.

The device has been qualified to meet the JEDEC
standard for Pb-Free assembly. The temperatures
and time intervals listed are based on the Pb-Free
small body requirements. The temperatures refer to
the topside of the package, measured on the
package body surface. The VS-500 device is
hermetically sealed so an aqueous wash is not an
issue.
