DESCRIPTION

^: Internal pull-up

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.
