MAX9234/MAX9236/ MAX9238 Hot-Swappable, 21-Bit, DC-Balanced LVDS Deserializers The MAX9234/MAX9236/MAX9238 deserialize three LVDS serial-data inputs into 21 single-ended LVCMOS/LVTTL outputs. A parallel-rate LVDS clock received with the LVDS data streams provides timing for deserialization. The outputs have a separate supply, allowing 1.8V to 5V output logic levels. All these devices are hot-swappable and allow “on-the-fly” frequency programming. The MAX9234/MAX9236/MAX9238 feature DC balance, which allows isolation between a serializer and deserializer using AC-coupling. Each deserializer decodes data transmitted by one of the MAX9209/MAX9211/ MAX9213/MAX9215 serializers. The MAX9234 has a rising-edge output strobe. The MAX9236/MAX9238 have a falling-edge output strobe. The MAX9234/MAX9236/MAX9238 operate in DCbalanced mode only. The MAX9234/MAX9236 operate with a parallel input clock of 8MHz to 34MHz, while the MAX9238 operates from 16MHz to 66MHz. The transition time of the singleended outputs is increased on the low-frequency version parts MAX9234/MAX9236 for reduced EMI. The LVDS inputs meet ISO 10605 ESD specification, ±25kV for AirGap Discharge and ±8kV Contact Discharge. The MAX9234/MAX9236/MAX9238 are available in 48-pin TSSOP packages and operate over the -40°C to +85°C temperature range.
