ATA5749 Fractional-N PLL Transmitter

ATA5749 Description

.
The Atmel® ATA5749 is a fractional-N-PLL transmitter IC for 300MHz to 450MHz operation and is especially targeted for Tire Pressure Sensor Gauges, Rem.

ATA5749 Features

* Fully Integrated Fractional-N PLL
* ASK and Closed Loop FSK Modulation
* Output Power Up to +12.5dBm from 300MHz to 450MHz
* Current Consumption is Scaled by Output Power Programming
* Fast Crystal Oscillator Start-up Time of Typically 200µs
* Low Cu

ATA5749 Applications

* It operates at data rates up to 40kbit/s Manchester for ASK and FSK with a typical 5.5dBm output power at 7.3mA. Transmitter parameters such as output power, output frequency, FSK deviation, and current consumption can be programmed using the SPI interface. This fully integrated PLL transmitter IC
