CC2500
CC2500 is RF Transceiver manufactured by Texas Instruments.
Description
The CC2500 is a low-cost 2.4 GHz transceiver designed for very low-power wireless applications. The circuit is intended for the 24002483.5 MHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band.
The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 500 k Baud.
CC2500 provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wake-on-radio.
The main operating parameters and the 64byte transmit/receive FIFOs of CC2500 can be
- Wireless audio
- Wireless keyboard and mouse
- RF enabled remote controls controlled via an SPI interface. In a typical system, the CC2500 will be used together with a microcontroller and a few additional passive ponents.
Key Features
RF Performance
- High sensitivity (- 104 d Bm at 2.4 k Baud, 1% packet error rate)
- Low current consumption (13.3 m A in RX, 250 k Baud, input well above sensitivity limit)
- Programmable output power up to +1 d Bm
- Excellent receiver selectivity and blocking performance
- Programmable data rate from 1.2 to 500 k Baud
- Frequency range: 2400
- 2483.5 MHz
Analog Features
- OOK, 2-FSK, GFSK, and MSK supported
- Suitable for frequency hopping and multi- channel systems due to a fast settling frequency synthesizer with 90 us settling time
- Automatic Frequency pensation (AFC) can be used to align the frequency synthesizer to the received centre frequency
- Integrated analog temperature sensor
Digital Features
