Press Release Summary:
Intended for Ethernet and Fibre Channel equipment, MAX3625B utilizes low-noise VCO and PLL architecture to generate high-frequency, low-jitter (0.36 psRMS) clock signal from low-frequency crystal resonator or reference clock input. Its -57 dBc PSNR minimizes jitter degradation and facilitates design in noisy system environments. Specified over -40 to +85Â°C range and operating from 3.3 V Â±5%, IC provides 3 LVPECL outputs up to 320 MHz from 2 programmable output-divider banks.
Original Press Release:
Precision Timing for High-Speed Data Communications
Clock generator creates high-frequency, ultra-low-jitter clock signals.
Maxim's three-output clock generator offers excellent jitter (0.36psRMS) and PSNR (-57dBc) performance to ensure precision timing in noisy system environments.
SUNNYVALE, CA-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX3625B high-performance, three-output clock generator for Ethernet and Fibre Channel equipment. This device utilizes a low-noise VCO and PLL architecture to generate a high-frequency, ultra-low-jitter (0.36psRMS) clock signal from a low-frequency crystal resonator or reference clock input. Its -57dBc PSNR minimizes jitter degradation and eases design in noisy system environments. The MAX3625B eliminates the expensive crystal oscillator and fanout buffer required by conventional solutions, as it only requires an external, AT-cut fundamental-mode crystal. Because it reduces the space requirements and cost of the total clock-distribution solution, this device is well suited for applications such as Ethernet switches/routers and storage-area network switches.
To further reduce the overall BOM, the MAX3625B provides three LVPECL outputs up to 320MHz from two output-divider banks. The output dividers are programmable, allowing designers to set these outputs to the frequencies required by their application.
The MAX3625B operates from 3.3V ±5% and is fully specified over the -40°C to +85°C extended temperature range. It is available in a small, 7.8mm x 4.4mm, lead-free, 24-pin TSSOP package. Prices start at $7.35 (1000-up, FOB USA).
