MAX9234/MAX9236/ MAX9238 Hot-Swappable, 21-Bit, DC-Balanced LVDS Deserializers General Description Features The MAX9234/MAX9236/MAX9238 deserialize three DC Balance Allows AC-Coupling for Wider Input LVDS serial-data inputs into 21 single-ended Common-Mode Voltage Range LVCMOS/LVTTL outputs. A parallel-rate LVDS clock On-the-Fly Frequency Programming received with the LVDS data streams provides timing for deserialization. The outputs have a separate supply, Operating Frequency Range allowing 1.8V to 5V output logic levels. All these devices 8MHz to 34MHz (MAX9234/MAX9236) are hot-swappable and allow on-the-fly frequency 16MHz to 66MHz (MAX9238) programming. Falling-Edge Output Strobe (MAX9236/MAX9238) The MAX9234/MAX9236/MAX9238 feature DC balance, which allows isolation between a serializer and deseri- Slower Output Transitions for Reduced EMI alizer using AC-coupling. Each deserializer decodes (MAX9234/MAX9236) data transmitted by one of the MAX9209/MAX9211/ High-Impedance Outputs when PWRDWN Is Low MAX9213/MAX9215 serializers. Allow Output Busing The MAX9234 has a rising-edge output strobe. The 5V-Tolerant PWRDWN Input MAX9236/MAX9238 have a falling-edge output strobe. The MAX9234/MAX9236/MAX9238 operate in DC- PLL Requires No External Components balanced mode only. Up to 1.386Gbps Throughput The MAX9234/MAX9236 operate with a parallel input clock of 8MHz to 34MHz, while the MAX9238 operates Separate Output Supply Pins Allow Interface to from 16MHz to 66MHz. The transition time of the single- 1.8V, 2.5V, 3.3V, and 5V Logic ended outputs is increased on the low-frequency version LVDS Inputs Meet ISO 10605 ESD Requirements parts (MAX9234/MAX9236) for reduced EMI. The LVDS inputs meet ISO 10605 ESD specification, 25kV for Air- LVDS Inputs Conform to ANSI TIA/EIA-644 LVDS Gap Discharge and 8kV Contact Discharge.
