APRIL 21, 2008 -- Maxim Integrated Products (search for Maxim) has introduced the MAX3674 wide-frequency-range, dual-output clock generator for high-speed system equipment. This device uses a low-noise VCO and PLL architecture to generate a 5-psec RMS jitter output clock up to 1,360 MHz from a low-frequency reference clock provided by the onboard 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 designed 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 3.3-V ±5% supply. It is available in a lead-free, 48-pin LQFP package. Prices start at $12.00 (1000-up, FOB USA).
