General
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
- 5 X 5mm QFN package with minimum RF parasitic
- Lead-free packaging and dice is available on request
