GENERAL DESCRIPTION
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.
