Atmel T5750
The T5750 is a PLL transmitter IC which has been developed for the demands of RF low-cost transmission systems at data rates up to 32 kBaud. The transmitting frequency range is 868 MHz to 928 MHz. It can be used in both FSK and ASK systems.FEATURES
● Integrated PLL Loop Filter● ESD Protection also at ANT1/ANT2 (4 kV HBM/200V MM; Except Pin 2: 4 kV HBM/100V MM)
● High Output Power (5.5 dBm) with Low Supply Current (8.5 mA)
● Modulation Scheme ASK/FSK – FSK Modulation is Achieved by Connecting an Additional Capacitor Between the XTAL Load Capacitor and the Open Drain Output of the Modulating Microcontroller Easy to Design-in Due to Excellent Isolation of the PLL from the PA and Power Supply Single Li-cell for Power Supply Supply Voltage 2.0V to 4.0V in the Temperature Range of –40°C to +85°C/+125°C Package TSSOP8L Single-ended Antenna Output with High Efficient Power Amplifier CLK Output for Clocking the Microcontroller One-chip Solution with Minimum External Circuitry 125°C Operation for Tire Pressure Systems
