2 HMCLPCE INTEGRATED VCO,. -.2 GHz General Description The HMCLPCE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) with an Integrated Voltage Controlled Oscillator (VCO). The input reference frequency range is 00 khz to 220 MHz while the advanced deltasigma modulator design in the fractional PLL allows both ultra-fine step sizes and very low spurious products. The highly integrated structure provides excellent phase noise performance over temperature, shock and process. The HMCLPCE is packaged in a leadless QFN x mm surface mount package. The output power is 5 dbm typical, making the HMCLPCE ideal for driving the LO port of many of Hittite s Hi Linearity and I/Q mixer products. For theory of operation and register map refer to the PLLs w/ Integrated VCO - Microwave VCOs Operating Guide. To view the Operating Guide, please visit and choose HMCLPCE from the Search by Part Number pull down menu.
