T5750

• Integrated PLL Loop Filter
• ESD Protection also at ANT1/ANT2 (4 kV HBM/200 V MM; Except Pin 2: 4 kV HBM/100 V 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 2.0 V to 4.0 V 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

The T5750 is a PLL transmitter IC which has been developed for the demands of RFlow-cost transmission systems at data rates up to 32 kBaud. The transmittingfrequency range is 868 MHz to 928 MHz. It can be used in both FSK and ASKsystems.
