Programmable DC-Balance
21-Bit Deserializers
General Description
The MAX9210/MAX9212/MAX9214/MAX9216/MAX9220/
MAX9222 deserialize three LVDS serial data inputs into
21 single-ended LVCMOS/LVTTL outputs. A parallel rate
LVDS clock received with the LVDS data streams pro-
vides timing for deserialization. The outputs have a sepa-
rate supply, allowing 1.8V to 5V output logic levels.
The MAX9210/MAX9212/MAX9214/MAX9216/MAX9220/
MAX9222 feature programmable DC balance, which
allows isolation between a serializer and deserializer
using AC-coupling. Each deserializer decodes data
transmitted by one of MAX9209/MAX9211/MAX9213/
MAX9215 serializers.
The MAX9210/MAX9212/MAX9214/MAX9216 have ris-
ing-edge output strobes, and when DC balance is not
programmed, are compatible with non-DC-balanced
21-bit deserializers such as the DS90CR216A and
DS90CR218A. The MAX9220/MAX9222 have falling-
edge output strobes.
Two frequency versions and two DC-balance default con-
ditions are available for maximum replacement flexibility
and compatibility with popular non-DC-balanced deserial-
izers. The transition time of the single-ended outputs is
increased on the low-frequency version parts (MAX9210/
MAX9212/MAX9220) for reduced EMI. The LVDS inputs
meet IEC 61000-4-2 Level 4 ESD specification, ±15kV for
Air Discharge and ±8kV Contact Discharge.
The MAX9210/MAX9212/MAX9214/MAX9216/MAX9220/
MAX9222 are available in TSSOP and space-saving QFN
packages, and operate over the -40°C to +85°C temper-
ature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
