Description
AI
Together with an external loop filter and a voltage controlled crystal oscillator (VCXO), the HMC1031 forms a complete clock generator solution targeted at low frequency jitter attenuation and reference clock generation applications.The HMC1031 features a low power integer N divider, support-ing divide ratios of 1, 5, and 10, which is controlled via external hardware pins and requires no serial port.The integrated phase detector and charge pump are capable of operating at up to 140 MHz, and a maximum VCXO input of 500 MHz ensures frequency compliance with a wide variety of system clocks and VCXOs.Additional features include an integrated lock detect indicator available on a dedicated hardware pin, and a built in power-down mode.The HMC1031 is housed in an 8-lead MSOP package.APPLICATIONSLow jitter clock generationLow bandwidth (BW) jitter attenuationLow frequency phase-locked loops PLLFrequency translationOven controlled crystal oscillator (OCXO) frequency multiplierPhase lock clean high frequency references to 10 MHz equipment
