PLL520-05/-06/-07/-08/-09
Low Phase Noise VCXO with multipliers (for 100-200MHz Fund Xtal)
FEATURES
• 100MHz to 200MHz Fundamental Mode Crystal.
• Output range: 100 – 200MHz (no multiplication),
200 – 400MHz (2x multiplier), 400 – 800MHz (4x
multiplier), or 800MHz – 1GHz (PLL520-09
TSSOP only, 8x multiplier).
• High yield design supports up to 2pF stray
capacitance at 200MHz.
• CMOS (Standard drive PLL520-07 or Selectable
Drive PLL520-06), PECL (Enable low PLL520-08
or Enable high PLL520-05) or LVDS output
(PLL520-09).
• Integrated variable capacitors.
• Supports 3.3V-Power Supply.
• Available in 16-Pin (TSSOP or 3x3mm QFN)
Note: PLL520-06 only available in 3x3mm.
Note: PLL520-07 only available in TSSOP.
DESCRIPTION
The PLL520-05/-06/-07/-08/-09 is a family of VCXO
ICs specifically designed to pull high frequency
fundamental crystals. Their design was optimized to
tolerate higher limits of interelectrode capacitance
and bonding capacitance to improve yield. They
achieve very low current into the crystal resulting in
better overall stability. Their internal varicaps allow
an on chip frequency pulling, controlled by the
VCON input.
