FEATURES
• 65MHz to 130MHz Fundamental Mode Crystal.
• Output range: 65MHz – 800MHz (selectable 1x,
2x, 4x and 8x multipliers).
• Low Injection Power for crystal 50uW.
• Available outputs: PECL, LVDS, or CMOS.
• Integrated variable capacitors.
• Supports 3.3V-Power Supply.
• Available in 16 pin (TSSOP or SOIC)
DESCRIPTION
The ABV2017/18/19 family of VCXO IC’s is
specifically designed to pull high frequency
fundamental crystals. 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.
