ATA5757 - UHF ASK/FSK TRANSMITTER

Download the ATA5757 datasheet PDF. This datasheet also covers the ATA5756 variant, as both devices belong to the same uhf ask/fsk transmitter family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • PLL transmitter IC with single-ended output.
  • High output power (6dBm) at 8.1mA (315MHz) and 8.5mA (433MHz) typical values.
  • Divide by 24 (Atmel® ATA5756) and 32 (Atmel ATA5757) blocks for 13MHz crystal frequencies and for Low XTO start-up times.
  • Modulation scheme ASK/FSK with internal FSK switch.
  • Up to 20kBaud manchester coding, up to 40kBaud NRZ coding.
  • Power-down idle and power-up modes to adjust corresponding current consumption through ASK/FSK/enable input pins.
