Description

The ATA5756/ATA5757 is a PLL transmitter IC which has been developed for the

demands of RF low-cost transmission systems at data rates up to 20 kBaud Manches-

ter coding and 40 kBaud NRZ coding. The transmitting frequency range is 313 MHz to

317 MHz (ATA5756) and 432 MHz to 448 MHz (ATA5757), respectively. It can be used

in both FSK and ASK systems. Due to its shorten crystal oscillator settling time it is

well suited for Tire Pressure Monitoring (TPM) and for Passive Entry Go applications.
