Embedded automotive applications can benefit from Mercury Electronics Europe’s new range of ultra-miniature, ultra-low phase noise crystal oscillators. The surface mount HJ22 oscillators offer 15pF load LVCMOS output at frequencies from 20 to 50MHz with typical RMS phase jitter of 48fs, 300fs maximum. Phase noise characteristics of -153dBc/Hz at 10kHz offset and -166dBc/Hz at 100kHz offset (49.152MHz output frequency, 3.3V input model) are said to be significantly better when compared with standard oscillators.
Measuring 2.5 by 2.0 by 0.9mm, the oscillators are available with 1.8, 2.5 or 3.3V power supply requirements and offer typical current consumption of 3mA, 5mA maximum. Frequency stability over both commercial (-10 to 70°C) and industrial (-40 to 85°C) can be specified as ±25, ±50 or ±100ppm as standard.
MEC Europe is an approved supplier to the automotive industry with IATF16949 approval, reinforcing the company’s commitment to longevity, ruggedness and design innovation in the taxing automotive component environment.
