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 dBm) with Low Supply Current (9.0 mA)
Modulation Scheme ASK/FSK
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
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
– FSK Modulation is Achieved by Connecting an Additional Capacitor between the XTAL Load Capacitor and the Open-
drain Output of the Modulating Microcontroller
