ATA8203/ATA8204/ATA8205

Description

The ATA8203/ATA8204/ATA8205 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 aftermarket keyless entry systems, and tire pressure monitoring

systems, telemetering, consumer/industrial remote control applications, home entertainment,

access control systems,and security technology systems. It can be used in the frequency receiv-

ing range of f

0 = 312.5 MHz to 317.5 MHz, f0 = 431.5 MHz to 436.5 MHz or f0 =868 MHz to

870 MHz for ASK or FSK data transmission. All the statements made below refer to 315 MHz,

433 MHz and 868.3 MHz applications.
