CC400DBR

RF Transceiver ICS Overview

The CC400DBR is a single-chip RF transceiver manufactured by Texas Instruments, designed for general ISM band applications below 1 GHz. It operates within the 300 MHz to 500 MHz frequency range and supports FSK modulation with a maximum data rate of 9.6 kbps. The device features a transmit power output of 14 dBm and a receiver sensitivity of -110 dBm. Power consumption is specified at 23 mA during reception, while transmission current ranges from 33 mA to 77 mA. It functions on a supply voltage between 2.7 V and 3.3 V and is housed in a 28-SSOP package.

RF Transceiver ICS Feature Summary

• Integrates high-performance RF transmitter and receiver circuits into a single chip for simplified design.
• Supports Frequency Shift Keying (FSK) modulation for reliable digital communication.
• Provides configurable configuration registers and interrupt capabilities for system control.

RF Transceiver ICS Applications

• Wireless sensor networks operating in sub-GHz bands
• Remote control systems requiring low power consumption
• Industrial telemetry and monitoring equipment

RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific revision level matches your design requirements. Check for end-of-life status as indicated by some sources. Ensure compatibility with your PCB footprint for the 28-SSOP package. Validate supply chain integrity to avoid counterfeit components.

RF Transceiver ICS Selection Notes

Select this component when designing systems requiring integrated TxRx functionality in the 300-500 MHz range. Consider the 2.7V to 3.3V supply constraint for battery-powered applications. Evaluate the 28-SSOP package size against available board space. Compare performance metrics like sensitivity and output power against alternative discrete solutions.

RF Transceiver ICS Part Context

This part belongs to the CC400 family of RF transceivers from Texas Instruments. It is distinct from I/O expanders such as the TCA9554ADBR or PCA9555DBR, which serve different interface functions. The CC400 series focuses on wireless communication rather than digital logic expansion.
