Low-jitter, dual-output clock generator provides wide frequency range for high-speed system equipment
(Product News, 29 Apr 2008 )
Maxim Integrated Products has launched the MAX3674 wide-frequency-range, dual-output clock generator for high-speed system equipment. This device utilizes a low-noise VCO and PLL architecture to generate a low, 5psRMS jitter output clock up to 1360MHz from a low-frequency reference clock provided by the on-board crystal oscillator or external LVCMOS clock. To reduce cost, it provides two differential LVPECL outputs for the same or different frequencies, thus eliminating one high-frequency crystal oscillator. Additionally, an I2C-compatible interface enables fine-tuning of the output frequency for frequency-margining testing, thus minimizing the complexity of system testing procedure. The MAX3674 is ideal for high-speed applications such as Ethernet switches/routers, storage-area-network switches, wireless base-station channel cards, and server clock generation.
The MAX3674 is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range, and operates from a 3.3V ±5% supply. It is available in a lead-free, 48-pin LQFP package. Prices start at $12.00 (1000-up, FOB USA).
