T5753

• Integrated PLL Loop Filter
• ESD Protection (4 kV HBM/ 200 V MM; Except Pin 2: 4 kV HBM/ 100 V MM) also at ANT1/ANT2
• High Output Power (8.0 dBm) with Low Supply Current (9.0 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 T5753 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 310 MHz to 330 MHz. It can be used in both FSK and ASKsystems.
