FEATURES
VCXO output for the 17MHz to 130MHz range
- PLL500-17B: 17MHz to 36MHz
- PLL500-27B: 27MHz to 65MHz
- PLL500-37B: 65MHz to 130MHz
Low phase noise (-142 dBc @ 10kHz offset).
CMOS output with OE tri-state control.
Selectable output drive (Standard or High drive).
- Standard: 8mA drive capability at TTL level.
- High: 24mA drive capability at TTL level.
Fundamental crystal input.
Integrated high linearity variable capacitors.
+/- 150 ppm pull range, max 5% linearity.
Low jitter (RMS): 2.5ps period jitter.
2.5 to 3.3V operation.
Available in 8-Pin SOIC or DIE.
DESCRIPTION
The PLL500-17B/27B/37B are a low cost, high per-
formance, low phase noise, and high linearity VCXO
family for the 17 to 130MHz range, providing less
than -130dBc at 10kHz offset. The very low jitter (2.5
ps RMS period jitter) makes these chips ideal for
applications requiring voltage controlled frequency
sources. The IC's are designed to accept fundamen-
tal resonant mode crystals.

Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permanent damage to the
device and affect product reliability. These conditions represent a stress rating only, and functional operations of the device at these or any other
conditions above the operational limits noted in this specification is not implied.
* Note: Operating Temperature is guaranteed by design for all parts (COMMERCIAL and INDUSTRIAL), but tested for COMMERCIAL grade only.

Note: The crystal must be such that it oscillates (parallel resonant) at nominal frequency when presented a C Load as specified above.
If the crystal requires more load to be at nominal frequency, the additional load must be added externally.
This however may reduce the pull range.
