Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX9225/MAX9226 serializer/deserializer chipset reduces wiring by serializing 10 bits onto a single differential pair. Ten bits are serialized in each cycle of the parallel input clock resulting in a 100Mbps to 200Mbps net serial-data rate. The MAX9225 serializes the 8-bit YUV, HSYNC and VSYNC outputs from a camera mounted in the flip part of the phone, reducing wiring through the hinge to the baseband processor in the base of the phone. The 2-wire serial interface uses low-current differential signaling (LCDS) for low EMI, high common-mode noise immunity, and ground-shift tolerance. The MAX9225/MAX9226 automatically identify the word boundary in the serial data in case of signal interruption.

The MAX9226 power-down is controlled by the MAX9225. The MAX9225/MAX9226 consume 3.5A or less in power-down mode.The MAX9225 serializer operates from a single +2.375V to +3.465V supply and accepts +1.71V to +3.465V inputs. The MAX9226 deserializer operates from a +2.375V to +3.465V core supply and has a separate output buffer supply (V_DDO), allowing +1.71V to +3.465V output high levels.

The MAX9225/MAX9226 are specified over the -40°C to +85°C extended temperature range and are available in 16-pin TQFN (3mm x 3mm x 0.8mm) packages with an exposed paddle.
