MAX9250ECM+

Serializers, Deserializers Overview

The MAX9250ECM+ is a 27-bit DC-balanced LVDS deserializer operating at parallel clock frequencies from 5MHz to 42MHz. It converts serial video data into 18 bits of parallel RGB output and control data into 9 bits of parallel CNTL output. The device features a separate VCCO supply for interfacing with 1.8V to 3.3V logic levels, while the core operates on a +3.3V ±10% supply. It includes an OUTEN input for output busing, selectable rising or falling latch edges via R/F, and ISO 10605 ESD protection rated at ±10kV contact discharge and ±30kV air-gap discharge.

Serializers, Deserializers Feature Summary

• Proprietary decoding ensures DC balance and reduces electromagnetic interference
• Output enable input allows multiple devices to bus outputs together
• Control data inputs are tolerant to single-bit errors during deserialization
• Staggered output switching minimizes ground bounce and EMI

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify that the component suffix 'ECM' corresponds to the specified -40°C to +85°C temperature range and LQFP package. Confirm the '+' suffix indicates lead-free compliance. Ensure the source document matches the official Maxim Integrated datasheet revision 5 dated June 2017 to validate all electrical parameters.

Serializers, Deserializers Selection Notes

Select the MAX9250 when output busing capability is required, as it provides an explicit OUTEN pin unlike the spread-spectrum enabled MAX9248. Ensure the reference clock frequency falls within the 5MHz to 42MHz operational window. Verify that the target logic interface voltage is compatible with the separate VCCO supply range of 1.8V to 3.3V.

Serializers, Deserializers Part Context

This component belongs to the MAX9248/MAX9250 family of digital video serial-to-parallel converters. It is designed to pair with the MAX9247 serializer for complete transmission systems or the MAX9217 serializer for frequencies below 35MHz. The ECM variant specifies the commercial temperature grade and physical package type.

Serializers, Deserializers Replacement Considerations

The MAX9248 is a functional alternative if spread-spectrum output generation is needed instead of busing. For lower frequency applications under 35MHz, the MAX9218 can be considered. Verify pin compatibility and software configuration requirements before substitution.
