Frequency Synthesizers with Sub-Picosecond Jitter Ease Timing Design for High-Speed Systems
Maxim has introduced the MAX3671/MAX3673 low-jitter, frequency synthesizers with nine phase-aligned LVPECL outputs for high-speed systems. These devices utilize a low-noise VCO and PLL architecture to generate high-frequency (312.5MHz), low-jitter (0.3psRMS) clock signals from a 62.5MHz reference-clock input. Configured through three 4-level control inputs, the MAX3671 simultaneously generates two different frequencies for both Ethernet port clocking and MAC clocking, while the MAX3673 generates outputs for CPRI/UMTS reference clocking (122.88MHz, 245.76MHz).
ThisThe MAX3671/MAX3673 are fully specified over the -45 degrees Celsius to +85 degrees Celsius extended temperature range, and operate from 3.3V ±5%. They are available in a lead-free, 56-pin TQFN package. Prices start at $10.26 (1000-up, FOB USA). Evaluation kits are available to speed designs.
