MAX2112CTI+T

RF Receivers Overview

The MAX2112CTI+T is a direct-conversion RF receiver IC designed for digital TV, CATV, and set-top box applications. It operates within a frequency range of 925MHz to 2.175GHz. The device integrates a voltage-controlled oscillator (VCO) and a complete fractional-N frequency synthesizer on a single chip. It utilizes a 28-WFQFN package with an exposed pad, measuring 5mm x 5mm. The supply voltage ranges from 3.13V to 3.47V, with a receive current of 100mA. It supports surface mount installation and functions within a temperature range of -40°C to +85°C.

RF Receivers Feature Summary

• Direct-conversion architecture compatible with DVB-S2 demodulators
• Provides gain control range exceeding 80dB

RF Receivers Applications

• Digital TV systems
• CATV infrastructure
• Set-top boxes

RF Receivers Procurement Notes

Verify the specific suffix 'CTI' against official Analog Devices documentation to confirm temperature grade and tape-and-reel packaging specifications. Ensure the 28-WFQFN footprint matches your PCB design requirements. Confirm RoHS compliance status as per the latest manufacturer datasheet before finalizing procurement orders.

RF Receivers Selection Notes

Select this component for designs requiring integrated frequency synthesis in the 925MHz to 2.175GHz band. Consider the 100mA receive current and 3.13V-3.47V supply range for power budgeting. Verify compatibility with DVB-S2 demodulators if used in satellite reception contexts. Ensure thermal management accounts for the exposed pad in the 28-TQFN package.

RF Receivers Part Context

The MAX2112 series belongs to Analog Devices' portfolio of RF receivers targeting broadcast and cable television markets. This specific variant, MAX2112CTI+T, represents the commercial temperature grade version packaged in tape and reel format. It is part of the broader MAX211x family which shares similar direct-conversion architectures but may differ in pinout or specific integration levels.

RF Receivers Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical parameters carefully when considering any substitute components.
