synthesized architecture. FM / FSK modulation is utilized to provide superior
performance and noise immunity over AM-based solutions. The ES Series is

offer a great deal of application flexibility to the designer. Some of these features,
which will be discussed in depth in this data guide, are:

PIN DESCRIPTIONS
The ES Series is offered in the 902-928MHz band, which is free from the legal
restrictions of the lower 260-470MHz band. This gives the designer much more

THEORY OF OPERATION
The ES Series FM / FSK transmitter is capable of generating 1mW of output
power into a 50-ohm load while suppressing harmonics and spurious emissions
to within legal limits. The transmitter is comprised of a VCO and a crystal-
controlled frequency synthesizer. The frequency synthesizer, referenced to a
precision crystal, locks the VCO to achieve a high-Q, low phase-noise oscillator.
The transmitter operates by directly modulating the crystal with the baseband

Analog Ground

signal present on the DATA line. Pulling the crystal in this manner achieves the
desired deviation and linearity. If the transmitter’s VCO were modulated, the
frequency synthesizer would track out much of the deviation within the
bandwidth of the loop filter (this is a common limitation of most synthesized FM
transmitters). The carrier is then amplified and filtered before being output on the
50-ohm ANT line.
The frequency of the Divided Clock output is determined by the state of the Clock
Frequeny Selection line. A low on the Select line will generate a signal on the
clock output that is the center frequency divided by 256, a high will be the center
frequency divided by 1,024.
