Five, chip introduction:

ADF4350/ADF4351 combined with external loop filter and the use of external reference frequency, can achieve a fractional N or integer N frequency (PLL) frequency synthesizer.

ADF4350/ADF4351 has an integrated voltage controlled oscillator (VCO), whose fundamental output frequency range is 2200 MHz to 4400 MHz. In addition, the use of 1/2/4/8/16 frequency divider circuit, the user can generate a low to MHz RF 35Mhz/137.5 output frequency. For applications that require isolation, the RF output stage can be implemented as a mute. Mute function can be controlled through the pin, but also through software control. At the same time to provide auxiliary RF output, and can not be shut off.

• Output frequency range: 137.5 MHz to 4400 MHz
• Frequency synthesizer and integer N frequency synthesizer with fractional N
• VCO with low phase noise
• Programmable 1/2/4/8/16 frequency output
• Root mean square (RMS) jitter: less than 0.4 RMS PS (typical value)
• Power supply voltage: 3 V to 3.6 V
• Logical compatibility: 1.8 V
• Programmable dual mode pre frequency divider: 4/5 or 8/9
• Programmable output power

• RF mute function
• Three wire serial interface
• Analog and digital lock detection
• Fast lock mode in wide band width
• Week jump
