Features

• Integrated PLL Loop Filter

• ESD Protection (4 kV HBM/200V MM; Except Pin 2: 4 kV HBM/100V MM) also at

ANT1/ANT2

• High Output Power (7.5 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 2.0V to 4.0V in the Temperature Range of –40°C to +85°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

1. Description

The ATA8402 is a PLL transmitter IC, which has been developed for the demands of

RF low-cost transmission systems for industrial applications at data rates up to

50 kBaud ASK and 32 kBaud FSK modulation scheme. The transmitting frequency

range is 429 MHz to 439 MHz. It can be used in both FSK and ASK systems.
