MAX9248GCM+T

Serializers, Deserializers Overview

The MAX9248GCM+T is a 27-bit DC-balanced LVDS deserializer operating at parallel clock frequencies from 5MHz to 42MHz. It converts serial LVDS input into 18 bits of parallel video data and 9 bits of control data. The device uses a +3.3V core supply with a separate VCCO output supply supporting 1.8V to 3.3V logic levels. It features programmable spread-spectrum outputs (±2% or ±4%) for EMI reduction, selectable rising/falling latch edges, and staggered switching. The component is housed in a 48-lead LQFP package and operates within temperature ranges of -40°C to +85°C or -40°C to +105°C.

Serializers, Deserializers Feature Summary

• Proprietary decoding provides DC balance and allows AC-coupling for interface isolation
• Programmable spread-spectrum capability reduces electromagnetic interference
• Control data deserialization occurs during video blanking periods
• Single-bit-error tolerance on five control data inputs via majority voting

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status as required by project specifications. Ensure the ordering code matches the exact functional variant needed for the design.

Serializers, Deserializers Selection Notes

Select this component when pairing with a MAX9247 serializer for complete digital video transmission. Use the MAX9248 variant specifically if spread-spectrum functionality is required for EMI mitigation. Verify that the operating frequency falls within the supported 5MHz to 42MHz range for proper synchronization.

Serializers, Deserializers Part Context

This part belongs to the MAX9248/MAX9250 family of 27-bit digital video serial-to-parallel converters. It functions as the receiver counterpart to the MAX9247 serializer. The GCM suffix indicates a specific commercial/industrial temperature grade and lead-free packaging configuration within the Maxim Integrated product line.

Serializers, Deserializers Replacement Considerations

The MAX9248ECM+ is a verified alternative within the same family offering identical electrical characteristics and pinout compatibility. Both devices support the same 48-lead LQFP package and operate under similar voltage and temperature constraints.
