Latest frequency control products for wide range of applications

Euroquartz exhibits its latest products at EDS 2022, including a new range of miniature temperature-compensated crystal oscillators (TCXO) providing frequency stability from ±2.5ppm and new UK-manufactured high-frequency voltage-controlled crystal oscillators (VCXO) providing ultra-low phase jitter performance. The new VCXO components are manufactured in the company’s class 7 cleanroom facility, and frequencies are available from 2MHz to 60MHz.

The new EM211T TCXO series provides frequencies from 10MHz to 60MHz with CMOS outputs in a miniature 2mm x 1.36mm x 0.7mm SMD package. Standard output frequencies available are 12, 20, 24, 25, 26, 40, 50 and 60MHz. These oscillators are ideal for a wide range of applications where high accuracy is essential with the miniature package making them suitable for embedded systems. With LVCMOS output into 15pF load, tolerances are available from ±2.5ppm to ±10ppm over the industrial temperature range (-40C to +85C), frequency dependent. Typical SSB phase noise at 25C ranges between -85Bc/Hz and -154dBc/Hz for 50MHz frequency output.

The new EG_JF VCXO series provides frequencies from 15MHz to 2100MHz for CMOS, LVPECL, LVDS and CML differential outputs and 15MHz to 700MHz for HCSL differential outputs. Excellent for a wide range of applications where ultra-low phase jitter is a prime condition, typical RMS phase jitter performance of the series ranges from as low as 151fs at 644.530MHz to 163fs at 2000MHz.

Also on show will be a surface mount clock oscillator capable of up to 3000G shock survivability with an extended temperature range. The EQXO-75UIE oscillator is a ruggedised LVCMOS-compatible circuit with a miniature quartz crystal housed in a low-profile ceramic surface mount package measuring 7mm x 5mm x 1.4mm. Designed by the company for demanding industrial applications, it provides reliable operation with good frequency stability across an extended industrial operating temperature band from -40C to +105C. Utilising the latest advances in production technology, combining optimised design and high-quality materials provides a high-reliability clock oscillator suitable for industrial applications.
