HMC984LP4E v02.0112 DIGITAL PHASE-FREQUENCY DETECTOR Typical Applications Features The HMC984LP4E is suitable for: Ultra-Low Noise: -231 dBc/Hz FOM Integer Mode Test Equipment -227 dBc/Hz FOM Fractional Mode Portable Instruments Ultra Low Spurious Emissions: High Performance Fractional-N Frequency - Less Than 60 dBc Fractional Spurious Synthesizers with Ultra Low Spurious Emissions Differential Phase Detector Input Military 14-bit Reference Frequency Divider Lock Indicator Output Phase Measurement Capability GPIO (General Purpose Input/Output) Test Pin Cycle Slip Prevention Support with HMC984LP4E 24 pin, 4 x 4 mm, LP4E Package Functional Diagram General Description HMC984LP4E is a high-performance, ultra-low phase noise, SiGe BiCMOS Phase-Frequency Detector and Charge Pump targeted to be used together with the HMC983LP5E (Fractional Frequency Divider) to together form a high performance, low noise, ultra low spurious emission fractional-N frequency synthesizer. Although best performance and maximum features are achieved when used together with the HMC983LP5E, the HMC984LP4E can also be used as a stand-alone, low phase noise phase frequency detector. The HMC984LP4E can receive differential VCO input, and a reference frequency as high as 150 MHz. It features a 14-bit reference frequency R-Divider, and automatic and/or configurable Lock Detect Indicator, as well as integrated CSP (Cycle Slip Prevention) capability, when used together with the HMC983LP5E, that significantly improves frequency lock time. Integrated Charge Pump phase swap option enables seamless interfaced to VCOs and active loop filters with inverted polarity. Additional features include adjustable Charge Pump gain and offset current that improve linearity and performance, and a Soft Reset feature that resets all register to default values without having to perform a power-cycle. The HMC984LP4E is housed in a compact 24 pin 4x4 mm LP4 package. Product covered by US and Foreign Patents including US Pat. No. 8,531,217.
