ClearClock Ultra-Low Jitter, Fixed-Frequency Miniature Clock Oscillator 2.5 x 2.0 x 1.0 mm AK2 ESD Sensitive RoHS/RoHS II Compliant Pb MSL = 1 Product Description TM Abracons latest addition to the ClearClock 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 -40C to +85C operating temperature range. The AK2 family offers best-in-class rms phase jitter of <110 fs typical at 156.25MHz carrier V = +2.5V with LVDS output, and dd is guaranteed to exhibit <200fs rms jitter 156.25MHz carrier with any bias voltage and RF output configuration. Features Applications Based on 3rd Overtone, Quartz Crystal Technology Optical Transceivers Ultra-low rms jitter < 120fs typical 156.25MHz Optical Modules Lowest in-class power consumption (15mA max with LVDS) Networking and communications 25ppm max & 30ppm max stability over -20C to +70C Gigabit Ethernet and -40C to +85C respectively Fibre Channel 3.3V, 2.5V & 1.8V supply voltage options SONET/SDH LVPECL, LVDS and HCSL differential output options RF systems, base stations (BTS) Output enabled (Active High standard default) Datacenter PCI Express Test & measurement Active cables Compact HD-SDI cameras Note 1 Options and Part Identification AK2 (6): Packaging (1): Output Blank: Bulk (***) (3): Stability over OTR P: LVPECL T: Tape & Reel 1,000 units D: 25ppm over -20C to +70C D: LVDS T3: Tape & Reel 3,000 units F: 30 ppm over -40C to +85C H: HCSL (***) MOQ: 100 units (2): V dd (5): Output Frequency A: 3.3V in MHz B: 2.5V (4): OE Function C: 1.8V (*) 1: OE Pin 1 Active High Please specify the frequency in units of MHz out to 2: OE Pin 2 Active High (*) Excluding 4 digit accuracy after the decimal.
