EVB72005

315MHz FSK/ASK Transmitter

Evaluation Board Description

Features

! Fully integrated PLL-stabilized VCO

! Frequency range from 290 MHz to 350 MHz

! Single-ended RF output

! FSK through crystal pulling allows modulation

from DC to 40 kbit/s

! High FSK deviation possible for wideband data

transmission

! ASK achieved by on/off keying of internal

power amplifier up to 40 kbit/s

! On-chip low voltage detector

! High over-all frequency accuracy

! FSK deviation and center frequency independ-

ently adjustable

! Adjustable output power range from

-12 dBm to +11 dBm (at connector board)

! Adjustable effective radiated power (ERP) range

from -31 dBm to -8 dBm (at antenna board)

! Adjustable current consumption from

3.2 mA to 10.3 mA

! Wide power supply range from 1.95 V to 5.5 V

! Very low standby current

! Conforms to FCC part 15 and similar standards

Ordering Information

Part No. (see paragraph 6)

EVB72005-315-FSK-A

EVB72005-315-FSK-C (on request)

Note 1: EVB default population is FSK, ASK modifications according to section 3.1 and 4.1.

Note 2: EVB72005 is applicable for devices TH72005, TH72001 and TH72002.

Application Examples

Evaluation Board Example

! General digital data transmission

! Tire Pressure Monitoring Systems (TPMS)

! Remote Keyless Entry (RKE)

! Wireless access control

! Alarm and security systems

! Garage door openers

! Remote Controls
