The document describes a voltage-controlled crystal oscillator for controlling crystal oscillation. It features high stability, wide frequency range, and adjustable parameters.
The ASV/ASV1 series crystal oscillators from Abracon are low‑profile, leadless chip carrier devices designed to provide precise clock signals for microprocessors, PC mainboards, and graphic cards. They operate with HCMOS/TTL compatible voltage levels (3.3 Vde, 2.5 Vdc, and 1.8 Vdc) and are suitable for high‑output‑drive applications.
Key features include RoHS compliance, seam‑welding and reflow capability, and a range of selectable options for frequency stability, temperature range, supply voltage, and packaging. Detailed electrical parameters, marking schemes, and optional configurations are listed to aid designers in selecting the appropriate part.
