NEW dual VCXO and high frequency TCXO from Vectron

Vectron International has launched three new FR4-based frequency control products. They are,

1. The VX-501 dual voltage controlled crystal oscillator (VCXO) with tight phase noise available in a 9x14 mm package.
2. FX-701 frequency translator in small package.
3. TX-702 high frequency Stratum 3 temperature controlled crystal oscillator (TCXO) in a 5x7 mm package.


The new VX-501 dual VCXO has two independent, selectable output frequencies from 20 to 700 MHz and the tightest phase noise available of any miniature, 9x14 mm VCXO on the market today. A complete solution, this product allows wireless designers to manufacture the board with one common BOM for all frequency bands, reducing the overall design complexity. The customer can design a base station for different frequency bands and select the frequency by software. In emerging wireless applications, sampling rates are increasing for wider bandwidths; therefore a clean reference clock with good phase noise is needed. The output signal is LVPECL and the supply voltage is 3.3 V. Typical phase noise is -90 dBc/Hz @ 100 Hz.

Vectron's FX-701 has input frequencies from 2 to 65 MHz and can be converted into output frequencies in the range of 10 to 185 MHz. Designed in a 5 x 7 mm package, the FX-701 saves space and reduces complexity, allowing customers to further miniaturize their systems. The new frequency translator offers the best phase noise performance at this size. Typical phase noise is -103 dBc/Hz @ 100 Hz. The output signal supported is LVCMOS and the supply voltage is 3.3 V.

Vectron's TX-702 high frequency TCXO operates at the highest frequencies available in a 5x7 mm package, up to 800 MHz with a stability of +/-280 ppb from -40 to 85 degrees Celsius. It meets Stratum 3 requirements for stability in wireline applications (GR-1244). The TX-702 features low jitter, 0.56 ps RMS (12 kHz to 20 MHz) at 622.08 MHz, has output signals LVPECL and LVDS, and the supply voltage is 3.3 V.
