Maxim Integrated Products released two new chipsets, the MAX9225/MAX9226 (10 bit) and the MAX9223/MAX9224 (22-bit) low-power lcds (low-current differential signaling) serializers

and deserializers, that communicate over a single twisted pair or differential line, which simplifies design, reduces cost and improves EMI.

The MAX9225 serializes 8 bits of LVTTL/LVCMOS RGB digital video data, 2 bits of LVTTL/LVCMOS control data and a clock into a single LCDS serial clock and data stream, while the MAX9226 deserializes a single LCDS serial input into 10 single-ended LVTTL/LVCMOS outputs.

The MAX9223 serializes 18 bits of LVTTL/LVCMOS RGB digital video data, 4 bits of LVTTL/LVCMOS control data, and a clock into a single LCDS serial clock and data stream. The MAX9224 deserializes a single LCDS serial input into 22 single-ended LVTTL/LVCMOS outputs.

According to Maxim, these SERDES chipsets provide significant savings in space and cost. They reduce the number of interconnect wires in clamshell phones from 11 to 2 (MAX9225/MAX9226) or from 23 to 2 (MAX9223/MAX9224). The MAX9225/MAX9226 chipset is designed for interfacing to image sensors with 8-bit-wide data output, and for simplifying data transmission in digital copiers and laser printers. Meanwhile, the MAX9223/MAX9224 are suitable for driving 320 x 240 resolution QVGA and QCIF LCD displays in cellphones, digital copiers and laser printers.

These SERDES operate from a 2.5V or 3.3V core supply and feature a separate supply for

interfacing to 1.8V to 3.3V logic levels. All devices are specified for operation from -40C to 85C. Inputs and outputs meet 15kV HBM (Human Body Model) ESD protection.

The MAX9225/MAX9226 are available in a 16-pin, 3-by-3mm TQFN package, and the MAX9223/MAX9224 are housed in a 28-pin, 4-by-4mm TQFN package. Prices start at 76 cents for the MAX9225/MAX9226 and $1.09 for the MAX9223/MAX9224 (25,000-up, FOB USA).
