Sunnyvale, Calif. - Maxim Integrated Products' MAX9209 21-bit low-voltage differential-signaling serializer offers users a programmable dc balance, which allows isolation between the serializer and deserializer by using ac coupling. The device serializes 21 bits of LVTTL/LVCMOS parallel inputs to three LVDS outputs.
A parallel-rate clock on the fourth channel provides timing for Maxim's upcoming MAX9210/MAX9212/MAX9214/MAX9220/MAX9222, the MAX9209's companion deserializers. The deserializers decode data transmitted by any of the companion serializers.
The serialization reduces the number of wires or traces from 22 to 8, saving space and cost in system interconnect applications such as cables and backplanes, according to Maxim. The LVDS input and output signals meet the requirements of the ANSI TIA/EIA-644 LVDS standard.
With its companion deserializers, the MAX9209 suits applications requiring high data rates.
Wide frequency range
The MAX9209 operates at a 8 MHz to 34 MHz parallel-clock frequency in dc-balanced mode and at 10 MHz to 40 MHz in non-dc-balanced mode. It requires a single 3.3-V plus/minus 10 percent supply and is specified for operation from -40 degrees C to 85 degrees C. The LVDS outputs meet IEC 61000-4-2 Level 4 ESD requirements of plus/minus 15 kV for air discharge and plus/minus 8 kV for contact discharge.
The MAX9209 is available in 48-pin TSSOP and QFN packages. Prices start at $3.90 in volumes of 1,000.
