General Description
The MAX9242/MAX9244/MAX9246/MAX9254 deserialize
three LVDS serial-data inputs into 21 single-ended LVC-
MOS/LVTTL outputs. A separate parallel-rate LVDS clock
provides the timing for deserialization. The MAX9242/
MAX9244/MAX9246/MAX9254 feature spread-spectrum
capability, allowing the output data and clock frequency
to spread over a specified range to reduce EMI. The sin-
gle-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
MAX9242/MAX9244/MAX9246/MAX9254 operate in non-
DC-balanced mode. The modulation rate of the spread is
32kHz for a 33MHz LVDS clock input and scales linearly
with frequency. The single-ended outputs have a sepa-
rate supply, allowing +1.8V to +5V output logic levels.
The MAX9254 features high output drive current for both
data and clock outputs for faster transition times in the
presence of heavy capacitive loads.
The MAX9242/MAX9244/MAX9246/MAX9254 feature pro-
grammable DC balance, allowing isolation between a
serializer and deserializer using AC-coupling. The
MAX9242/MAX9244/MAX9246/MAX9254 operate with the
MAX9209/MAX9213 serializers and are available with a
rising-edge strobe (MAX9242) or falling-edge strobe
(MAX9244/MAX9246/MAX9254). The LVDS inputs meet
ISO 10605 ESD specifications with ±30kV Air-Gap
Discharge and ±6kV Contact Discharge ratings.
