The LMK04033 is a precision low noise programmable jitter cleaner, clock multiplier, and distribution device. The LMK04033, with two internal PLLs and an extremely high performance internal LC voltage controlled oscillator (VCO), can be combined with a low cost VCXO module or an external crystal and varactor diode to achieve ultra low jitter performance over all bandwidths. The LMK04033 has redundant reference clock inputs with loss of signal detection, featuring automatic revertive, automatic non-revertive, or manual selection of the reference clock. The LMK04033 is ideal for clocking high speed high resolution ADCs, DACs, local oscillators and FPGAs with its wide range of low phase noise output selections. The LMK04033 is particularly well suited for all the clocking needs of remote transceivers, high performance instruments and other applications that demand ultra low jitter and phase noise using local clock sources.
