AST3

RoHS

7.0 x 5.0 x 2.0mm

Compliant

FFEEAATTUURREESS: :

APPLICATIONS:

• High Precision over temperature (±0.37 ppm over

-40ºC to + 85ºC)

• Excellent long term stability (±4.60 ppm Max. over 20-Year life)

• Small Profile (7*5*2 mm)

• Low Power (< 6mA CMOS; < 3.5mA Sinewave)

• Exceptional Close-in Phase Noise (-140 dBc/Hz @ 1kHz typ;

12.80MHz carrier)

• Wireless & Wireline communications

• Cellular Infrastructure

• Point-to-Point Radios

• Broadband Equipment

• Test & Measurement Equipment

• GPS tracking with precision hold-over accuracy
