Serializer and Deserializer Chipset
General Description
The MAX9225/MAX9226 serializer/deserializer chipset
reduces wiring by serializing 10 bits onto a single differ-
ential 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 mount-
ed 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 differ-
ential 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 3.5µA 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 (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.
