LMX2594
Overview
The LMX2594 is a high-performance, wideband synthesizer that can generate any frequency from 10 MHz to 15 GHz without using an internal doubler, thus eliminating the need for sub-harmonic filters. The high-performance PLL with.
- 1 10-MHz to 15-GHz output frequency
- -110 dBc/Hz phase noise at 100-kHz offset with 15-GHz carrier
- 45-fs rms jitter at 7.5 GHz (100 Hz to 100 MHz)
- Programmable output power
- PLL key specifications - Figure of merit: -236 dBc/Hz - Normalized 1/f noise: -129 dBc/Hz - High phase detector frequency - 400-MHz integer mode - 300-MHz fractional mode - 32-bit fractional-N divider
- Remove integer boundary spurs with programmable input multiplier
- Synchronization of output phase across multiple devices
- Support for SYSREF with 9-ps resolution programmable delay
- Frequency ramp and chirp generation ability for FMCW applications
- < 20-µs VCO calibration speed
