AK1F3/AK2F3 ClearClock™ Oscillators

Abracon AK1F3/AK2F3 ClearClock™ Oscillators offer high-frequency crystal technology and exceptional low-jitter performance. These oscillators provide a supply voltage of 2.5V or 3.3V with LVPECL or LVDS (standard and high swing) output logic type. The AK1F3/AK2F3 ClearClock oscillators feature an output frequency of 312.5MHz, a standby (power down) function, and a hermetically seam-sealed ceramic package. These oscillators are available in a compact package with an all-inclusive frequency stability of ±20ppm over an operating temperature range of -40°C to 105°C. The AK1F3/AK2F3 ClearClock oscillators are rated MSL Level 1 and are REACH/RoHS II compliant. Typical applications include optical transceivers and modules, data centers, storage, servers, networking switches, gateways, 100G/200G/400G/800G Ethernet, industrial, and FPGA.
