ATA8403
UHF ASK/FSK Industrial Transmitter
DATASHEET
Features
● Integrated PLL loop filter ● ESD protection (3kV HBM/150V MM) ● High output power (5.5dBm) with low supply current (8.5mA) ● 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
Applications
● Industrial/aftermarket remote keyless entry systems ● Alarm, telemetering, and energy metering systems ● Remote control systems for consumer and industrial markets ● Access control systems ● Home a.
