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 DC-balanced
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 single-ended
outputs is increased on the low-frequency version
parts (MAX9234/MAX9236) for reduced EMI. The LVDS
inputs meet ISO 10605 ESD specification, ±25kV for Air-Gap 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.
