Miniature ICs Boost Crystal Oscillator Performance

A new line of voltage-controlled crystal oscillator (VCXO) ICs serves to maximize system performance by providing a stable, low noise clock reference for precise transmission and processing of data. The VCXO Clock The generator ICs are suited for a wide range of applications in which cost, size, power and the number of discrete components need to be minimized. Available in either die or SOIC packages, these VCXO ICs are designed to exhibit excellent temperature stability and phase noise performance. The T228 and T229 incorporate a programmable divider that allows the user to select output frequencies lower than the crystal frequency while providing 50% output symmetry. The T230 has a PLL that allows the user to select output frequencies that are multiples of the crystal frequency while also providing 50% output symmetry.
