LMX2820
Overview
The LMX2820 is a high-performance, wideband synthesizer that can generate any frequency in the range of 45 MHz to 22.6 GHz. The high performance PLL with.
- Output frequency: 45 MHz to 22.6 GHz
- 36-fs rms jitter (12 kHz - 95 MHz) at 6 GHz
- High-performance PLL - Figure of merit: -236 dBc/Hz - Normalized 1/f noise: -134 dBc/Hz - -95 dBc Integer Mode Spurs (fPD=100 MHz) - High phase detector frequency
- 400-MHz integer mode
- 300-MHz fractional mode - Programmable input multiplier - Direct PFD input for offset mixing support allowing PLL N divider to be one for ultra-low jitter
- 2.5-µs fast VCO calibration time
- Mute pin with 200-ns mute/unmute time
- -45-dBc VCO leakage with doubler enabled
- Support for external VCO up to 22.6-GHz
- Synchronization of output phase across multiple devices
