ATA5723/ATA5724/ATA5728
The ATA5723/ATA5724/ATA5728 is a multi-chip PLL receiver device supplied in an SSO20
package. It has been specially developed for the demands of RF low-cost data transmission sys-
tems with data rates from 1 kBit/s to 10 kBbit/s in Manchester or Bi-phase code. Its main
applications are in the areas of keyless entry systems, tire pressure monitoring systems, teleme-
tering, and security technology systems. It can be used in the frequency receiving range of
f
ASK or FSK data transmission. All the statements made below refer to 315 MHz, 433 MHz and
868.3 MHz applications.
