PLL502-51 Datasheet, PDF (1/5 Pages) PhaseLink Corporation – Low Phase Noise VCXO (20MHz to 52MHz)

PLL502-51
Low Phase Noise VCXO (20MHz to 52MHz)
FEATURES
• Integrated voltage-controlled crystal oscillator
circuitry (VCXO) (pull range 380ppm minimum).
• VCXO tuning range: 0V - V_DDV.
• Uses inexpensive fundamental-mode parallel
resonant crystals (from 20 to 52MHz).
• 2.5V or 3.3V supply voltage.
• Selectable High Drive (30mA) or Standard Drive
(10mA) CMOS output.
• Available in 8-Pin SOIC or TSSOP.
DESCRIPTION
The PLL502-51 is a monolithic low jitter, high per-
formance CMOS VCXO IC. It allows control of the
output frequency with an input voltage (VCON), us-
ing a low cost crystal.
This makes the PLL502-51 ideal for a wide range of
applications from 20MHz to 52MHz (including
27MHz, 35.328MHz, etc.).
