The receive part is built as a fully integrated receiver, whereas direct PLL modulation with the synthesizer is used for FSK transmission and switching of the power amplifier for ASK transmission. The device supports data rates of 1 kBaud to 20 kBaud FSK and 1 kBaud to 10 kBaud ASK in Manchester, and other codes in transparent mode. The ATA5428 can be used in the MHz to MHz and in the 862 MHz to 872 MHz bands, the ATA5423 in the MHz to MHz band, the ATA5425 in the MHz to MHz band and the ATA5429 in the MHz to MHz band. The very high system integration level results in a small number of external components needed. Due to its blocking and selectivity performance, together with the additional 15 dB to 20 dB loss and the narrow bandwidth of a typical loop antenna in a remote control unit, a bulky blocking SAW is not needed in the remote control unit. Additionally, the building blocks needed for a typical remote control and access control system on both sides the base and the mobile stations are fully integrated. Its digital control logic with and protocol generation enables a fast response system without using a microcontroller. Therefore, the ATA5423/ATA5425/ATA5428/ATA5429 contains a FIFO buffer RAM and can compose and receive the physical messages themselves. This provides more time for the microcontroller to carry out other functions such as calculating crypto algorithms, composing the logical messages, and controlling other devices. Therefore, a standard microcontroller without special periphery and clocked with the CLK output of about MHz is sufficient to control the communication link. This is especially valid for passive entry and access control systems, where within less than 100 ms several communications with arbitration of the communication partner have to be handled. It is hence possible to design remote control and access control systems with a fast crypto function, with the same PCB board size and with the same current consumption as remote control systems.
