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. Their very low jitter makes them ideal for the most demanding timing requirements. 1 VDD DESCRIPTION VDD VCON 65MHz to 130MHz Fundamental Mode Crystal. Output range: 65MHz - 130MHz (no PLL). Low Injection Power for crystal 50uW. PECL (ABV2038) or LVDS output (ABV2039). Integrated variable capacitors. Supports 2.5V or 3.3V-Power Supply. Available in 16-Pin (TSSOP or 3x3 QFN).
