Maxim Integrated Products introduces the latest members of the company's high-speed LVDS serializer-deserializer (SerDes) products, the MAX9217 and MAX9218, which serialize 27 lines into a single DC-balanced twisted pair or differential line for improved EMI and low-cost routing. DC-balancing reduces the effects of low-frequency ground fluctuations while the serial LVDS link reduces the number of wires or traces from 28 to 2, saving cost and dramatically reducing EMI. The LVDS inputs and outputs meet the requirements of the ANSI TIA/EIA 644 LVDS standard.
The MAX9217 serializer and MAX9218 deserializer are ideal for 480 x 800 resolution LCD displays, automotive navigation and entertainment systems, digital copiers, laser printers, network switches/routers, and base stations.
The MAX9217 serializes 18 bits of LVTTL/LVCMOS RGB digital video data, 9 bits of LVTTL/LVCMOS control data, and clock into a single LVDS serial clock and data stream. The MAX9218 deserializes a single LVDS serial input into 27 single-ended LVTTL/LVCMOS outputs. The MAX9217 and MAX9218 feature DC-balanced outputs, which use AC coupling to allow isolation between serializer and deserializer. The DC-balanced feature reduces bit errors in the MAX9218 deserializer due to shift in the common mode caused by ground shift. The maximum aggregate payload data rate is 700Mbps.
The MAX9217 operates from a 3.3V (±10%) core supply and features a separate input supply for interfacing to 1.8V to 3.3V logic levels.
The MAX9218 features a separate output supply for interfacing to 1.8V to 3.3V logic-level inputs. Both devices are specified for operation from -40 degrees Celsius to +85 degrees Celsius. The LVDS inputs and outputs meet the ISO 10605 specification (±30kV air, ±10kV contact).
The MAX9217 and MAX9218 are available in 48-pin TQFP or QFN packages.
Prices start at $6.15 for each part, $12.30 per chipset (1000-up, FOB
