ADF7012
FEATURES
GENERAL DESCRIPTION
Single-chip, low power UHF transmitter
The ADF7012 is a low power FSK/GFSK/OOK/GOOK/ASK
75 MHz to 1 GHz frequency operation
UHF transmitter designed for short-range devices (SRDs). The
Multichannel operation using fractional-N PLL
output power, output channels, deviation frequency, and mod-
2.3 V to 3.6 V operation
ulation type are programmable by using four, 32-bit registers.
On-board regulator Programmable output power
−16 dBm to +14 dBm, 0.4 dB steps Data rates: dc to 179.2 kbps Low current consumption
868 MHz, 10 dBm, 21 mA 433 MHz, 10 dBm, 17 mA 315 MHz, 0 dBm, 10 mA Programmable low battery voltage indicator 24-lead TSSOP
The fractional-N PLL and VCO with external inductor enable the user to select any frequency in the 75 MHz to 1 GHz band. The fast lock times of the fractional-N PLL make the ADF7012 suitable in fast frequency hopping systems. The fine frequency deviations a.
