MAX9271GTJ+T

Overview

The MAX9271GTJ+T is a compact serializer designed to drive 50Ω coax or 100Ω shielded twisted-pair (STP) cable, pairing with the MAX9272 deserializer. It supports up to 16-bit parallel inputs and achieves serial bit rates of up to 1.5Gbps. The device operates on core supplies of 1.7V to 1.9V and I/O supplies of 1.7V to 3.6V. It features an embedded control channel operating at 9.6kbps to 1Mbps in UART modes or up to 400kbps in I²C mode. The component includes programmable pre/deemphasis, spread spectrum modulation, and error detection/correction coding. It is housed in a 32-pin TQFN-EP package measuring 5mm x 5mm and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Supports double-rate clocking for megapixel camera applications by registering two pixels before serialization.
• Features an embedded control channel allowing microcontroller programming of registers independent of video timing.
• Includes programmable pre/deemphasis and spread spectrum output to reduce EMI and extend cable transmission distance.
• Provides peripheral features such as built-in PRBS generators for BER testing and dedicated GPIO ports for frame synchronization.

Applications

• Automotive camera systems
• Megapixel image sensor interfaces
• Coax or STP cable drive links

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and environmental rating. Confirm that the requested variant matches the required automotive qualification standards. Ensure compatibility with the paired MAX9272 deserializer for system integration. Check current availability status through authorized distributors as supply conditions may vary.

Selection Notes

Select this serializer when driving 50Ω coaxial or 100Ω STP cables is required for high-speed video transmission. Consider the double-input capability if higher pixel clock frequencies are needed compared to single-input configurations. Verify that the system design accommodates the specified core and I/O voltage ranges. Ensure the application environment falls within the -40°C to +105°C operating temperature limits.
