DATA SHEET

SKY72300-362: Spur-Free, 2.1 GHz Dual Fractional-N

Frequency Synthesizer

Applications

• Direct digital modulation

• 3 V operation

• General purpose RF systems

• 2.5G and 3G wireless infrastructure

• Broadband wireless access

• Low bit rate wireless telemetry

• Instrumentation

• 5 V output to loop filter

• QFN (24-pin, 4 x 4 mm) Pb-free (MSL3, 260 °C per JEDEC J-

STD-020) package

Description

• L-band receivers

Skyworks SKY72300-362 direct digital modulation fractional-N

frequency synthesizer provides ultra-fine frequency resolution,

fast switching speed, and low phase-noise performance. This

synthesizer is a key building block for high-performance radio

system designs that require low power and fine step size.

• Satellite communications

Features

• Spur-free operation

The ultra-fine step size of less than 100 Hz allows this synthesizer

to be used in very narrowband wireless applications. With proper

temperature sensing or through control channels, the

synthesizer’s fine step size can compensate for crystal oscillator

or Intermediate Frequency (IF) filter drift. As a result, crystal

oscillators or crystals can replace temperature-compensated or

ovenized crystal oscillators, reducing parts count and associated

component cost. The device’s fine step size can also be used for

Doppler shift corrections.

• 2.1 GHz maximum operating frequency

• 500 MHz maximum auxiliary synthesizer

• Ultra-fine step size, 100 Hz or less

• High internal reference frequency enables large loop bandwidth

implementations

• Very fast switching speed (e.g., below 100 µs)

• Phase noise to –91 dBc/Hz inside the loop filter bandwidth

The SKY72300-362 has a phase noise floor of –90 dBc/Hz up to

2.1 GHz operation as measured inside the loop bandwidth. This is

permitted by the on-chip low noise dividers and low divide ratios

provided by the device’s high fractionality.

@ 1800 MHz

• Software programmable power-down modes

• High-speed serial interface up to 100 Mbps

• Three-wire programming

Reference crystals or oscillators up to 50 MHz can be used with

the SKY72300-362. The crystal frequency is divided down by

independent programmable dividers (1 to 32) for the main and

auxiliary synthesizers. The phase detectors can operate at a

maximum speed of 25 MHz, which allows better phase noise due

to the lower division value. With a high reference frequency, the

loop bandwidths can also be increased. Larger loop bandwidths

improve the settling times and reduce in-band phase noise.

Therefore, typical switching times of less than 100 s can be

achieved. The lower in-band phase noise also permits the use of

lower cost Voltage Controlled Oscillators (VCOs) in customer

applications.

• Programmable division ratios on reference frequency

• Phase detectors with programmable gain to provide a

programmable loop bandwidth

• Frequency power steering further enhances rapid acquisition

time

• On-chip crystal oscillator

• Frequency adjust for temperature compensation

Skyworks offers lead (Pb)-free RoHS (Restriction of

Hazardous Substances) compliant packaging.

The SKY72300-362 has a frequency power steering circuit that

helps the loop filter to steer the VCO when the frequency is too

fast or too slow, further enhancing acquisition time.
