FEATURES

• 100MHz to 200MHz Fundamental Mode Crystal.

• Output range: 100 – 200MHz (no multiplication),

200 – 400MHz (2x multiplier), 400 – 800MHz (4x

multiplier), or 800MHz – 1GHz (ABV2009

TSSOP only, 8x multiplier).

• High yield design supports up to 2pF stray

capacitance at 200MHz.

• CMOS (Standard drive ABV2007 or Selectable

Drive ABV2006), PECL (Enable low ABV2008 or

Enable high ABV2005) or LVDS output

(ABV2009).

• Integrated variable capacitors.

• Supports 3.3V-Power Supply.

• Available in 16-Pin (TSSOP or 3x3mm QFN)

Note: ABV2006 only available in 3x3mm.

Note: ABV2007 only available in TSSOP.

DESCRIPTION

The ABV2005/-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.
