The LMX2820RTCR from Texas Instruments is a wideband RF synthesizer designed for high-performance applications. It can generate frequencies ranging from 45 MHz to 22.6 GHz, making it suitable for demanding RF systems.
Key electrical specifications include a low jitter of 36-fs rms (at 6 GHz, 12 kHz–95 MHz bandwidth) and a high-performance Phase-Locked Loop (PLL) with a figure of merit of -236 dBc/Hz. The device also offers a normalized 1/f noise of -134 dBc/Hz and integer mode spurs of -95 dBc at 100 MHz PFD frequency. It supports high phase detector frequencies of 400 MHz in integer mode and 300 MHz in fractional mode.
Designed for ease of integration, the LMX2820RTCR operates from a single 3.3-V supply and includes integrated LDOs. It features a fast VCO calibration time of 2.5 µs, enabling rapid frequency hopping. The synthesizer supports synchronization of output phase across multiple devices and provides two differential RF outputs and one differential SYSREF output, compliant with the JESD204B standard.
This component is available in a 48-VFQFN exposed pad package and is designed for surface mount applications. Its operating temperature range is -40°C to 85°C.
