PLL502-00
Multiplier VCXO IC Die for 12 to 25MHz Parallel Resonant Crystals
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.).
