High-frequency programmable TCXO features fast delivery
The TXF temperature compensated crystal oscillator is the new TCXO from Total Frequency Control. This TXF offers the output of LVCMOS, LVPECL and LVDS with the frequency range from 10MHz up to 1.4GHz, supplied in the incredibly small package of 3.2x2.5mm.
Frequency oscillators offer a range of options
Manufactured over a frequency range of 1MHz to 200MHz, the miniature ceramic smd, crystal clock oscillator from Total Frequency Control (TFC) features a low supply current, tight symmetry and a supply voltage from 1.8V DC up to 3.3V DC. Output frequency is pre-programmed from standard units providing custom frequencies with minimum delivery times, suitable for new designs in miniature equipment, supplied on tape and reel.
32.768kHz smd tuning fork crystals
The sub miniaturisation of the ubiquitous 32.768 kHz ‘watch crystal’ continues with package sizes reduced to (2.0 x 1.2) mm and very low profile. Available from TFC, smd tuning fork crystals are a low cost crystal with an ultra-low profile of 0.9mm and three standard packages of 2.0 x 1.2mm, 3.2 x 1.5mm and 4.2 x 1.5mm.
High value inductance radial ferrite inductors
Supplied by Total Frequency Control the type PK radial inductors provide compact high value inductance. The use of high performance ferrite material results in high Q components from 1µH ~ 150milli H. A unique lead to winding construction method provides excellent mechanical strength and the product is epoxy coated for maximum protection against humidity and may additionally be sleeved to customers order.
SMD crystal oscillators enable ultra-low noise
TFC’s wide range of Crystal Oscillators has been updated with the introduction of two ultra Low Phase Noise oscillator packages, the OX-U (3.2x2.5 mm) and OY-U (2.5x2.0mm) SMD Crystal Oscillator packages. Both oscillators are available from 20 to 60MHz in frequency and are supplied in a small SMD package.
High frequency SMD crystals enable up to 400.0MHz
TFC’s range of quartz crystals have been updated with the introduction of two miniature crystal packages, the XX (3.20x2.50mm) and the XV (5.0x3.2mm). Both crystals are available up to 400MHz in frequency and are supplied in an ultra-thin SMD ceramic package with a vacuum seal.
Adjustable coils suitable for generic replacements
The I.F. adjustable coils are available in many different designs and sizes; they can be for generic replacements, standard or custom wound, tuneable shielded or unshielded. Suitable for oscillator circuits or as an IFT for AM/FM applications, TFC’s I.F. adjustable inductor coils are custom wound and manufactured with short lead times to meet sample and production requirements.
Lightweight oscillator designed for space saving
The recently available FCXO-06T is a compact and lightweight 2.0x1.6mm design which is suitable for space saving designs. This oscillator has precise frequency stability +/-8ppm over Operating Temperature of -40 +105°C and low power consumption of 3.0mA max. The frequency range from 2 - 80MHz.
The 'world’s smallest' quartz crystal unit
Recently available from River Electronics the FCX-08 package, which is classified as the world’s smallest quartz crystal unit. This crystal is enclosed in a ceramic 1.2×1.0mm package with a metal lid sealed by an electron beam. This particular package comes with a now lower frequency tolerance of +/- 7ppm and also with a wider operating temperature of -40 + 125°C. Frequencies range from 36 up to 80MHz, applications for this unique...
Small SMD power inductor features ferrite core
