Programmable DC-Balance
21-Bit Deserializers
General Description
Features
♦ Programmable DC Balance or Non-DC Balance
The MAX9210/MAX9214/MAX9220/MAX9222 deserialize
three LVDS serial data inputs into 21 single-ended LVC-
MOS/LVTTL outputs. A parallel rate LVDS clock received
with the LVDS data streams provides timing for deserial-
ization. The outputs have a separate supply, allowing
1.8V to 5V output logic levels.
♦ DC Balance Allows AC-Coupling for Wider Input
Common-Mode Voltage Range
♦ As Low as 8MHz Operation (MAX9210/MAX9220)
♦ Falling-Edge Output Strobe (MAX9220/MAX9222)
♦ Slower Output Transitions for Reduced EMI
The MAX9210/MAX9214/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/MAX9213 serializers.
(MAX9210/MAX9220)
♦ High-Impedance Outputs when PWRDWN is Low
Allow Output Busing
♦ Pin Compatible with DS90CR216A/DS90CR218A
(MAX9210/MAX9214)
The MAX9210/MAX9214 have rising-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.
♦ Fail-Safe Inputs in Non-DC-Balanced Mode
♦ 5V Tolerant PWRDWN Input
♦ PLL Requires No External Components
♦ Up to 1.785Gbps Throughput
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/MAX9220) for reduced EMI. The LVDS inputs
meet IEC 61000-4-2 Level 4 ESD specification, 15kV for
Air Discharge and 8kV Contact Discharge.
♦ Separate Output Supply Pins Allow Interface to
1.8V, 2.5V, 3.3V, and 5V Logic
♦ LVDS Inputs Meet IEC 61000-4-2 Level and ISO
10605 ESD Requirements
♦ LVDS Inputs Conform to ANSI TIA/EIA-644 LVDS
Standard
♦ Low-Profile 48-Lead TSSOP Package
♦ +3.3V Main Power Supply
♦ -40°C to +85°C Operating Temperature Range
The MAX9210/MAX9214/MAX9220/MAX9222 are avail-
able in a TSSOP package, and operate over the -40°C to
+85°C temperature range.
