Sunnyvale, Calif. Maxim Integrated Products has added three members to its high-speed low-voltage differential signaling (LVDS) SerDes family.
The MAX9234, MAX9236 and MAX9238 are hot-swappable, 21-bit, DC-balanced LVDS devices that can deserialize three LVDS serial inputs into 21 single-ended LVTTL/LVCMOS outputs, and communicate over a three-wire twisted pair or differential line.

Each device reduces the number of wires or traces to 8 from 22, which simplifies design and saves space and lowers cost in system interconnects such as cables or backplanes. Hot-swappable capability increases fault tolerance and allows quick frequency programming.
The LVDS outputs meet the requirements of the ANSI TIA/EIA 644 LVDS standard.
The MAX9234/MAX9236 deserializers are ideal for driving 480 X 800 resolution LCD displays, automotive navigation and entertainment systems, digital copiers, laser printers, network switches/routers, and base stations. The MAX9238's high clock rate is suitable for driving 768 X 1024 resolution LCD displays.
By using AC coupling, DC-balanced outputs allow isolation between the serializer and deserializer. The DC-balanced feature reduces bit errors due to shift in the common mode caused by ground shift. The maximum, aggregate payload data rate is 1.386-Gbits/s.
All three deserializers feature a separate output supply for interface to 1.8-V to 5-V logic-level inputs, and are specified for operation from -40° to +85°.
The MAX9234, MAX9236 and MAX9238 are available in a 48-pin, low-profile TSSOP package. Prices start at $3.90 in volumes of more than 1,000.
