ATA5757 Description
ATA5756/ATA5757 UHF ASK/FSK Transmitter DATASHEET.
ATA5757 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
- 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
- ENABLE input for parallel usage of controlling pins in a 3-wire bus system
- CLK output switches ON if the crystal current amplitude has reached 35% to 80% of its
- Crystal oscillator time until CLK output is activated, typically 0.6ms
- Supply voltage 2.0V to 3.6V in operation temperature range of -40°C to +125°C
