ATA8205P6C-TKQW

The 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 systems with data rates from 1Kbit/s to 10Kbit/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 receiving range of f0 = 312.5MHz to 317.5MHz, f0 = 431.5MHz to 436.5MHz or f0 = 868MHz to 870MHz for ASK or FSK data transmission.
