The MAX9232 deserializes three LVDS serial-data inputs into 21 single-ended LVCMOS/LVTTL outputs. A separate parallel-rate LVDS clock provides the timing for deserialization. The MAX9232 features spread-spectrum capability, allowing the output data and clock frequency to spread over a specified range to reduce EMI. The single-ended data and clock outputs are programmable for a frequency spread of 2%, 4%, or no spread. The spread-spectrum function is also available when the MAX9232 operates in non-DC-balanced mode. The modulation rate of the spread is 32kHz for a 33MHz LVDS clock input and scales linearly with frequency. Using VSYNC on RxOUT13 and HSYNC on RxOUT6, a reset of the spread-spectrum FIFO is performed every frame, preventing FIFO overflow and underflow. The single-ended outputs have a separate supply, allowing +1.8V to +5V output logic levels. The MAX9232 features programmable DC balance, allowing isolation between a serializer and deserializer using AC-coupling. The MAX9232 operates with the MAX9209/MAX9213 serializer and has a falling-edge strobe. The LVDS inputs meet ISO 10605 ESD specifications with 25kV Air-Gap Discharge and 8kV Contact Discharge ratings.
