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.
