Deserializers Promote High Data Rates

For applications requiring high-speed data transfers, the MAX9220 and MAX9222 21-bit LVDS deserializers convert three LVDS serial data streams into 21 single-ended LVTTL and LVCMOS outputs. Both employ a falling-edge output strobe and a programmable dc balance, which allows isolation between the serializer and deserializer via ac coupling. This dc-balanced topology reduces bit errors in the deserializer due to changes in the common mode incurred ground shifts. The MAX9222 operates at a parallel-clock frequency of 16 MHz to 66 MHz in balanced mode and 20 MHz to 85 MHz in non-balanced mode. The MAX9220 functions at a parallel clock frequency of 8 MHz to 34 MHz in balanced mode and 10 MHz to 40 MHz in non-balanced mode. To reduce EMI, transition times of the single-ended outputs are increased on the MAX9220. Shared features include operation from a 3.3V ±10% supply and an operating temperature range from -40°C to +85°C. Available in 48-pin TSSOP and QFN packages, prices are $6.30 for the MAX9222 and $3.90 for the MAX9220 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
