MAXIM ANNOUNCES INDUSTRY'S FIRST 3.2Gbps ADAPTIVE CABLE EQUALIZER/DRIVER
SUNNYVALE, CA—January 30, 2001—Maxim Integrated Products introduces the MAX3800 adaptive equalizer, enabling low-cost copper system interconnections at data rates up to 3.2Gbps. The MAX3800 is a +3.3V adaptive cable equalizer and a cable driver on a single chip. The MAX3800 effectively extends the usable length of coaxial and twin-axial copper cable in high-frequency interconnect applications by equalizing differential or single-ended signals at data rates up to 3.2Gbps. It automatically adjusts to attenuation caused by skin effect levels of up to 30dB at 1.6GHz, making 30m cables at less than $1.65 per meter (like RG179B) viable interconnect solutions.
The cable driver accepts differential or single-ended current-mode logic (CML) input data at rates up to 3.2Gbps and features adjustable CML output levels between 500mV and 1000mV. The equalizer includes differential CML data inputs and outputs, a TTL loss-of-signal (LOS) output, and a cable integrity monitor (CIM) output. All CML interfaces include on-chip terminations to reduce external component count. When the cable driver is set to maximum output voltage swing and the equalizer is compensating for 30dB of loss, typical power consumption is only 200mW. The driver can be disconnected from the power supply when it is not needed.
The MAX3800 is available in a 32-pin TQFP package with exposed pad and operates from a 3.3V supply over a 0°C to +85°C temperature range. The MAX3800 is priced at $9.96 (1000-up, suggested resale, FOB USA). Evaluation kits are available.
