| 2.4 GHZ ISM BAND TRANSCEIVER/FRAMER IC | |
| Description | |
The EM198810 is a CMOS integrated circuit that performs all functions from the antenna to the microcontroller
for transmission and reception of a 2.4GHz digital data. This transceiver IC integrates
most of the functions required for data transmission into a single integrated circuit. Additionally, the
programmability implemented reduces significantly external components count, board space
requirements and external adjustments. |
|
Features |
|
Combines 2.4 GHz GFSK RF transceiver with 8-bit data framer function |
|
|
Eliminates need for external software or hardware FIFO; offloads MCU for other tasks |
|
|
Simple microprocessor interface – 4 wires for SPI, plus 3 wires for RST/buffer control |
|
|
Each transmit, receive buffer is 64 bytes deep |
|
|
Long packets are possible if buffers are read/written before overflow/underflow occurs |
|
|
Always 1Mbps over-the-air symbol rate, regardless of MCU speed or architecture |
|
|
Preamble can be 1 to 8 bytes |
|
|
Supports 1, 2, 3, or 4 word address (up to 64 bits) |
|
|
Various Payload data formats to eliminate DC offset, enhance receive clock recovery and BER |
|
|
Programmable data whitening |
|
|
Supports Forward Error Correction (FEC): none, 1/3, or 2/3 |
|
|
Supports 16-bit CRC |
|
|
Baseband output clock available |
|
|
Power management for minimizing current consumption |
|
|
5x5mm QFN package with minimum RF parasitic |
|
|
Lead-free packaging and dice is available on request |
|
