Low Jitter Oscillators Ready For 10-Gb Ethernet Systems

Designed for 10-Gb Ethernet applications, the SM7745DV 156.25-MHz and 161.1328-MHz osillators sport a jitter specification of 0.15 psRMS from 12 kHz to 20 MHz. Over a temperature range from 0¡C to 70¡C, they exhibit a standard frequency stability of ±50 ppm, with a tighter ±25 ppm available as an option. Input voltage for both devices is 3.3V ±5%, with 2.5V also available. Typical rise and fall times are 1.5 ns, and again faster times can be requested. Both devices are TTL/CMOS compatible and come in an industry-standard 5 mm x 7 mm, leadless ceramic package. Pricing is from $7 each/10,000/mo. PLETRONICS INC., Lynnwood, WA. (425) 776-1880.
