MAX9222
Programmable DC-Balance 21-Bit Deserializers
Industry's First 21-Bit, Programmable DC-Balance Deserializers Deserialize Three LVDS Serial Data Inputs into 21 Single-Ended LVCMOS/LVTTL Outputs
Part Details
- Programmable DC Balance or Non-DC Balance
- 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 (MAX9210/MAX9220)
- High-Impedance Outputs when Active-Low PWRDWN is Low Allow Output Busing
- Pin Compatible with DS90CR216A/DS90CR218A (MAX9210/MAX9214)
- Fail-Safe Inputs in Non-DC-Balanced Mode
- 5V Tolerant Active-Low PWRDWN Input
- PLL Requires No External Components
- Up to 1.785Gbps Throughput
- 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 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.
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.
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.
Two frequency versions and two DC-balance default conditions are available for maximum replacement flexibility and compatibility with popular non-DC-balanced deserializers. 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.
The MAX9210/MAX9214/MAX9220/MAX9222 are available in a TSSOP package, and operate over the -40°C to +85°C temperature range.
