FEATURES

· Integrated voltage-controlled crystal oscillator

circuitry (VCXO) (pull range 500ppm minimum).

· Low phase noise (-130dBc @ 10kHz offset at

44MHz output)

· Selectable frequency multipliers (x1, x2, x4, x8).

· 3.3V supply voltage.

· Uses inexpensive fundamental-mode parallel

resonant crystals (from 12 to 25MHz).

· Selectable High Drive (30mA) or Standard Drive

(10mA) output.

· Available in DIE (65 mil x 62 mil).

DESCRIPTION

The PLL502-00 is a monolithic low jitter and low
phase noise (-130dBc @10kHz offset at 44MHz
output), high performance CMOS VCXO IC Die, that
uses a low cost crystal (12-25MHz).
The same die can be used as a VCXO with output
frequencies ranging from F

XIN

x 1 to F

XIN

x 8 using

selector pad bonding options (see Multiplier
Selection Table on this page). This makes the
PLL502-00 ideal for a wide range of applications
from 12MHz to 190MHz (including 27MHz,
35.328MHz, 77.76MHz and 155.52MHz, etc.).

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: Crystal Loading rating: 9.5pF is the loading the crystal sees from the VCXO chip at VCON = 1.65V. It is assumed that the crystal will be at
nominal frequency at this load. 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.
