The MAX9225/MAX9226 is a serializer/deserializer chipset ideal for serializing the parallel interface of cell phone cameras. It can serialize 10-bit data onto a single differential pair, reducing wiring. Ten bits are serialized in each cycle of the parallel input clock, resulting in a net serial-data rate of 100Mbps to 200Mbps. 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. In case of signal interruption, the MAX9225/MAX9226 automatically identifies the word boundary in the serial data. The MAX9226 power-down is controlled by the MAX9225. The MAX9225/MAX9226 consume 3.5µA 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 (VDDO), 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.
The MAX9225 and MAX9226 are low‑power 10‑bit serializer/deserializer chipsets designed for cell‑phone camera interfaces. They reduce wiring by converting parallel video data to a single differential pair, supporting data rates from 100 Mbps to 200 Mbps.
