Technical Description
The SKY72300-362 is a fractional-N frequency synthesizer using
a
Σ modulation technique. The fractional-N implementation
provides low in-band noise by having a low division ratio and fast
frequency settling time. In addition, the SKY72300-362 provides
arbitrarily fine frequency resolution with a digital word, so that the
frequency synthesizer can be used to compensate for crystal
frequency drift in the RF transceiver.
Serial Interface
The serial interface is a versatile three-wire interface consisting of
three pins: Clock (serial clock), Data (serial input), and CS (chip
select). It enables the SKY72300-362 to operate in a system
where one or multiple masters and slaves are present. To perform
a loopback test at startup and to check the integrity of the board
and processor, the serial data is fed back to the master device
(e.g., a microcontroller or microprocessor unit) through a
programmable multiplexer. This facilitates hardware and software
debugging.
Registers
There are ten 16-bit registers in the SKY72300-362. For more
information, see the Register Descriptions section of this
document.
Main and Auxiliary
Σ Modulators
The fractionality of the SKY72300-362 is accomplished by the use
of a proprietary, configurable 10-bit or 18-bit
Σ modulator for
the main synthesizer and 10-bit
Σ modulator for the auxiliary
synthesizer.
Main and Auxiliary Fractional Units
The SKY72300-362 provides fractionality through the use of main
and auxiliary
Σ modulators. The output from the modulators is
combined with the main and auxiliary divider ratios through their
respective fractional units.
VCO Prescalers
The VCO prescalers provide low-noise signal conditioning of the
VCO signals. They translate from an off-chip, single-ended or
differential signal to an on-chip differential Current Mode Logic
(CML) signal. The SKY72300-362 has independent main and
auxiliary VCO prescalers.
Main and Auxiliary VCO Dividers
The SKY72300-362 provides programmable dividers that control
the CML prescalers and supply the required signals to the charge
pump phase detectors. Programmable divide ratios ranging from
38 to 537 are possible in fractional-N mode and from 32 to 543 in
integer-N mode.
Reference Frequency Oscillator
The SKY72300-362 has a self-contained, low-noise crystal
oscillator. This crystal oscillator is followed by the clock
generation circuitry that generates the required clock for the
programmable reference frequency dividers.
