Fairport, NY, USA: Saelig Company, Inc. (Fairport, NY) has launched a new range of surface-mount temperature-compensated crystal oscillators (TCXO) offering a frequency stability as low as ±2.5ppm. The new EM211T series is available with CMOS outputs in frequencies from 10 to 60MHz. The standard output frequencies available are 12, 20, 24, 25, 26, 40, 50 and 60MHz. The components are housed in a standard format 6-pad 2.0 x 1.36mm SMD ceramic package with hermetically sealed metal lid. Power supply voltage options are 1.8, 2.5 and 3.3V ±5% with current consumption of 8mA maximum at 3.3V.
The new EM211T series oscillators are ideal for use in applications where high accuracy and a miniature package is important, making these TCXOs particularly suitable for embedded and portable systems. With LVCMOS output into a 15pF load, frequency dependent tolerances are available from ±2.5 to ±10ppm over the industrial temperature range (-40 to +85°C). Typical SSB phase noise at 25°C is between -85 and -154dBc/Hz for 50MHz frequency output. Frequency stability is specified as ±1.0ppm maximum against aging in first year, ±0.3ppm maximum against voltage change for ±5% change, ±0.3ppm maximum against load change for ±10% change and ±1.0ppm maximum against reflow (SMD type) for one reflow, measured after 24 hours.
Additional specifications include rise/fall time of 10ns maximum, duty cycle of 50% ±5% as standard and output enable/disable function as standard. Initial calibration tolerance is less than ±2ppm at 25°C ±2°C. Storage temperature range is -55 to +125°C.
Made in Europe by frequency specialist Euroquartz Ltd., the EM211T series TCXOs are available from their technical distributor Saelig.
