T5760

T5760 / T5761 UHF ASK/FSK Receiver Description The T5760/T5761 is a multi-chip PLL receiver device supplied in an SO20 package. It has been especially developed for the demands of RF low-cost data transmission systems with data rates from 1 kBaud to 10 kBaud in Manchester or Bi-phase code. The receiver is well suited to operate with the Atmel Wireless & Microcontrollers’ PLL RF transmitter T5750. Its main applications are in the areas of telemetering, security technology and keyless-entry systems. It can be used in the frequency receiving range of f0 = 868 to 870 MHz or f0 = 902 to 928 MHz for ASK or FSK data transmission. All the statements made below refer to 868.3 MHz and 915.0 MHz applications. Features D Fully integrated LC-VCO and PLL loop filter D Very high sensitivity with power matched LNA D 30 dB image rejection D High system IIP3 (–16 dBm), system 1-dB compression point (–25 dBm) D High large-signal capability at GSM band (blocking –30 dBm @ + 20 MHz, IIP3 = –12 dBm @ + 20 MHz) D 5 V to 20 V automotive compatible data interface D Data clock available for Manchester- and Bi-phasecoded signals D Programmable digital noise suppresion D Receiving bandwidth BIF = 600 kHz for low cost 90-ppm crystals D Low power consumption due to configurable polling D Temperature range –40°C to 105°C D ESD protection 2 kV HBM, 200 V MM D Communication to mC possible via a single bi-directional data line D Low-cost solution due to high integration level with minimum external circuitry ...
