ATA5757

ATA5756/ATA5757 UHF ASK/FSK Transmitter DATASHEET 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 ● 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 final value ● 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 ● ESD protection at all pins (4kV HBM) ● Small package TSSOP10 Benefits ● Low parasitic FSK switch integ...
