T48C862-R3

4554A–4BMCU–02/03

UHF ASK/FSK Transmitter Block

Features

• 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

– 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

• 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

Description

The PLL transmitter block has been developed for the demands of RF low-cost transmission systems, at data rates up to

32 kbaud. The transmitting frequency range is 310 MHz to 330 MHz. It can be used in both FSK and ASK systems.
