XCLK1
Multi-Channel Clock Generator is an ideal source for analog to digital converter sample clock for DSP applications because it was designed with embedded computing in mind by providing a clock source, with up to six phase-matched outputs, packaged in a convenient PMC or XMC board form factor.
Overview
The XCLK1 Multi-Channel Clock Generator is an ideal source for analog to digital converter sample clocks for DSP applications including Signal Intelligence (SIGINT), Spectral Analysis, and Radar. The XCLK1 Multi-Channel Clock Generator is different because it was designed with embedded computing in mind by providing a clock source, with up to six phase-matched outputs, packaged in a convenient PMC/XMC board form factor.
The XCLK1 from Curtiss-Wright provides several clock source options including an internal temperature-compensated crystal oscillator or off-board RF or off-board 10 MHz references. The 10 MHz reference sources are used to drive low-phase noise VCO/PLL frequency multiplication circuitry (each frequency output is a build variant). Local frequency multiplication based on the 10 MHz temperature compensated crystal oscillator (TCXO) can generate output signals in the range of 500 MHz to over 2 GHz with a jitter of less than 0.5ps. Single-ended and differential clock outputs are supported.
The XCLK1 is carefully engineered to synchronize multiple ADC/DAC cards within a compact XMC form factor, typically integrated into an SBC, optimizing space utilization while avoiding the use of unnecessary system slots.
