ADF4351 35MHz-4.4GHz PLL RF Signal Source Frequency Synthesizer Board
Using the ADF4351 35MHz-4.4GHz PLL RF Signal Source Frequency Synthesizer Board from PMD Way you can produce sine waves from 35 Mhz to 4.4 GHz - with crystal accuracy.
The ADF4351 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and external reference frequency.
The ADF4351 has an integrated voltage controlled oscillator (VCO) with a fundamental output frequency ranging from 2200 MHz to 4400 MHz. In addition, divide-by-1/-2/-4/-8/-16/-32/-64 circuits allow the user to generate RF output frequencies as low as 35 MHz.
For applications that require isolation, the RF output stage can be muted. The mute function is both pin- and software-controllable. An auxiliary RF output is also available, which can be powered down when not in use.
- Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT)
- Test equipment
- Wireless LANs, CATV equipment
- Clock generation
It runs from 5V DC and has two outputs, one 180 degrees out of phase with the other - allowing it to produce either single-ended or differential signals. Control is via the SPI data bus at 3.3V.
Althouth the board is powered by 5V DC via tha jack socket, logic is only 3.3V so you will need a level converter for working with 5V DC development boards.
