MAX9250ECM/V+T

Serializers, Deserializers Overview

The MAX9250ECM/V+T is a 48-lead LQFP digital video serial-to-parallel converter designed for automotive applications. It deserializes a total of 27 bits, converting an LVDS serial input into 18 bits of parallel video data and 9 bits of parallel control data. Operating at a reference clock frequency of 5MHz to 42MHz, it supports a maximum serial data rate of 840Mbps. The device features a separate output supply (VCCO) allowing interface to 1.8V to 3.3V logic levels while the core operates from a +3.3V ±10% supply. It includes an output enable input for busing, selectable rising or falling latch edges, and proprietary decoding for DC balance.

Serializers, Deserializers Feature Summary

• Proprietary data decoding provides DC balance and reduces electromagnetic interference
• Output enable input allows multiple devices to bus outputs together
• Control data is deserialized during video blanking periods
• Five control data inputs feature single-bit-error tolerance

Serializers, Deserializers Applications

• Navigation system displays
• In-vehicle entertainment systems
• Video cameras
• LCD displays

Serializers, Deserializers Procurement Notes

Verify the specific suffix 'ECM/V+T' against official documentation to confirm package type, temperature range, and tape-and-reel status. Confirm current availability as this component family may be subject to discontinuation notices. Ensure the ordering information matches the exact manufacturer part number requirements.

Serializers, Deserializers Selection Notes

Select the MAX9250 when output busing capability is required, as opposed to the MAX9248 which offers spread-spectrum EMI reduction. Ensure the operating frequency falls within the 5MHz to 42MHz range. Verify that the target logic voltage levels are compatible with the separate VCCO supply configuration.

Serializers, Deserializers Part Context

This component belongs to the MAX9248/MAX9250 family of 27-bit DC-balanced LVDS deserializers. It is typically paired with the MAX9247 serializer to form a complete digital video transmission system. For frequencies below 35MHz, it can also pair with the MAX9217 serializer.

Serializers, Deserializers Replacement Considerations

The MAX9248GCM+ is a functional substitute within the same family but lacks the output enable feature required for busing. Verify pin compatibility and ensure the application does not require the MAX9248's spread-spectrum capabilities if replacing with the MAX9250.
