MAX9209EUM+T

Serializers, Deserializers Overview

The MAX9209EUM+T is a programmable DC-balanced serializer that converts 21 bits of LVTTL/LVCMOS parallel input data into three LVDS serial outputs. It operates with a supply voltage range of +3.0V to +3.6V and supports an operating temperature range from -40°C to +85°C. The device features up to 1.785Gbps throughput, integrated output resistors (110Ω for DC-balanced mode, 410Ω for non-DC-balanced mode), and meets IEC 61000-4-2 and ISO 10605 ESD requirements. It is housed in a 48-lead TSSOP package.

Serializers, Deserializers Feature Summary

• Integrated PLL requires no external components and supports low-frequency operation down to 8MHz
• LVDS outputs conform to ANSI TIA/EIA-644 standards and meet specific EMI/ESD requirements
• Pin-compatible with DS90CR215 and DS90CR217 serializers in non-DC-balanced mode

Serializers, Deserializers Applications

• Automotive Navigation Systems
• Automotive DVD Entertainment Systems
• Digital Copiers
• Laser Printers

Serializers, Deserializers Procurement Notes

Verify the component status as discontinued or obsolete through official manufacturer channels before design finalization. Confirm RoHS compliance and lead-free packaging specifications using the current datasheet revision. Ensure the ordering suffix matches the required temperature range and package type for the intended application environment.

Serializers, Deserializers Selection Notes

Select this serializer when interfacing 21-bit parallel LVTTL/LVCMOS sources to LVDS receivers. Choose the DCB/NC pin configuration based on whether AC-coupling is required for ground shift isolation. Ensure the system clock frequency falls within the supported ranges for the selected operational mode to maintain signal integrity and timing margins.

Serializers, Deserializers Part Context

This component belongs to the MAX9209/MAX9213 family of programmable DC-balanced 21-bit serializers manufactured by Analog Devices Inc./Maxim Integrated. It serves as a high-speed interface solution for converting parallel digital data streams into serialized differential signals suitable for long-distance transmission over twisted-pair cables.

Serializers, Deserializers Replacement Considerations

The MAX9209 is pin-compatible with the DS90CR215 and DS90CR217 in non-DC-balanced mode. Verify functional equivalence and electrical characteristics against these legacy parts if direct replacement is required in existing designs.
