U2740B
UHF AM/FM Transmitter
Description
The U2740B-B is an one-chip multi-purpose UHF
ASK/FSK transmitter IC designed for various applica-
tions within a wide frequency range. When a
Chip-Select
(CS) signal is supplied, the IC starts operation (Power-up,
XTO, VCO, PD) and the VCO is then locked to
128 f(XTO). The locked status is indicated at the
Lock-Detect
(LD) output.
The digital data is supplied to either an AM- or FM-input
pin, the output power being set via the AM-input pin. A
differential output enables simple applications with loop
antennas. An output driver (XTO_out) can be used for
clocking the microcontrolller.
