family of ultra-low rms jitter oscillators is now available in a miniature 2.5 x 2.0 x
1.0 mm package. The AK2 family is based on 3rd overtone quartz crystal technology and is ideally suited for optical transceivers,
networking and server systems. AK2 family is available with bias voltages of 3.3V and 2.5V for LVDS & LVPECL output
configuration; and 3.3V, 2.5V & 1.8V for HCSL differential output. Production-ready frequencies include 100, 125, 148.5, 156.25
and 200MHz with better than ±30 ppm frequency stability over -40°C
to +85°C operating temperature range.
The AK2 family offers best-in-class rms phase jitter of <110 fs typical at 156.25MHz carrier @ V
dd
= +2.5V with LVDS output, and
is guaranteed to exhibit <200fs rms jitter @ 156.25MHz carrier with any bias voltage and RF output configuration.
