GENERAL DESCRIPTION
The Aeroflex Laboratories transceiver model ACT4444 is a monolithic transceiver which provides full compliance with Macair and MIL-STD-1553 data bus requirements. The model ACT4444 performs the front-end analog function of inputting and outputting data through a transformer to a MIL-STD-1553 or Macair data bus with a few external components.
The ACT4444 can be considered a "Universal" Transceiver in that it is compatible with MIL-STD-1553A, B, Macair A-3818, A-4905, A-5232 and A-5690.
Design of these transceivers reflects particular attention to active filter performance. This results in low bit and word error rate with superior waveform purity and minimal zero crossover distortion. The ACT4444 active filter design has additional high frequency roll-off to provide the required Macair low harmonic distortion waveform without increasing the pulse delay characteristics significantly.
Efficient transmitter electrical and thermal design provides low internal power dissipation and heat rise at high and well as low duty cycles.
An optional receiver input threshold adjustment can be accomplished by the use of the "External Threshold" terminals.

FEATURES
*Transceiver meets MIL-STD-1553A & B, Macair A3818, A4905, A5232 and A5690 specs
*Bipolar Supply ±15V to ±12V, Logic Supply +5V

Description
The Elan EM198810 IC is a low-cost, fully integrated CMOS radio frequency (RF) transceiver block, combined with a 64-byte buffered framer block. The RF transceiver block is a self-contained, fast-hopping GFSK data modem, optimised for use in the widely available 2.4 GHz ISM band. It contains transmit, receive, VCO and PLL functions, including an on-chip channel filter and resonator, thus minimizing the need for external components. The receiver utilizes extensive digital processing for excellent overall performance, even in the presence of interference and transmitter impairments. Transmit power is digitally controlled. The low-IF receiver architecture results in sensitivity to -80dBm or better, with impressive selectivity.
In normal applications, the EM198810 is connected to a low cost microcontroller(ex:EM78P451S).
In normal application The on-chip framer processes and stores the RF data in the background, unloading this critical timing function from the MCU. This lowers MCU speed requirements, expedites product development time, and frees the MCU for implementing additional product features.
The framer register settings determine the over-the-air formatting characteristics. Many configurations are possible, depending on the user’s specific needs. Raw transmit data is easily sent over-the-air as a complete frame of data, with preamble, address, payload, and CRC. Receiving data is just the opposite, using the preamble to train the receiver clock recovery, then the address is checked, then the data is reverse formatted for receive, followed by CRC. All of this is done in hardware to ease the programming and overhead requirements of the baseband MCU.
For longer battery life, power consumption is minimized by automatic enabling of the various transmit, receive, PLL, and PA sections, depending on the instantaneous state of the chip. A sleep mode is also provided for ultra low current consumption.
This product is available in 32-lead 5x5 mm JEDEC standard QFN package, featuring an exposed pad on the bottom for best RF characteristics. Lead-free RoHS compliant packaging is available on request.

FEATURES
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.
Key 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

GENERAL DESCRIPTION
The ML2726 is a fully integrated 2.0Mbps frequency shift keyed (FSK) transceiver that operates in the unlicensed 2.4GHz ISM frequency band. The device has been optimized for digital cordless telephone applications and includes all the frequency generation, receive and transmit functions. Automatically adjusted filters eliminate mechanical tuning. Closed loop modulation eliminates frequency drift and permits practically unlimited TX duration.
