Saelig Launches New Range of Euroquartz TCXOs with Output Frequencies from 10 to 60 MHz

Saelig, a US electronic component distributor has launched a new range of surface-mount temperature-compensated crystal oscillators (TCXO) from Euro Quartz. The new EM211T Series is available with CMOS outputs in frequencies from 10 to 60 MHz. The standard output frequencies available are 12, 20, 24, 25, 26, 40, 50 and 60 MHz. The components are housed in a standard 6-pad 2.0 x 1.36 mm SMD ceramic package with a hermetically sealed metal lid. Power supply voltage options are 1.8, 2.5 and 3.3 V ±5% with a maximum current consumption of 8 mA at 3.3 V.

The new EM211T Series of TCXOs 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 15 pF load, frequency-dependent tolerances are available from ±2.5 to ±10 ppm over the industrial temperature range (-40 to +85°C). Typical SSB phase noise at 25°C is between -85 and -154 dBc/Hz for 50MHz frequency output.  Frequency stability is specified as ±1.0 ppm maximum against aging in the first year, ±0.3 ppm maximum against voltage change for ±5% change, ±0.3 ppm maximum against load change for ±10% change and ±1.0 ppm maximum against reflow (SMD type) for one reflow, measured after 24 hours.

Additional specifications include a rise/fall time of 10 ns maximum, a duty cycle of 50% ±5% as standard and output enable/disable function as standard. Initial calibration tolerance is less than ±2 ppm at 25°C ±2°C. The storage temperature range is -55 to +125°C.

Made in Europe by frequency specialist Euroquartz, the EM211T Series TCXOs are available from their technical distributor Saelig.
