1. Description

The ATA8403 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 868 MHz to 928 MHz. It can be used in both FSK and ASK systems.

Integrated PLL Loop Filter

ESD Protection also at ANT1/ANT2

(4 kV HBM/200V MM; Except Pin 2: 4 kV HBM/100V MM)

High Output Power (5.5 dBm) with Low Supply Current (8.5 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 2.0V 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
