MAX2870ETJ+ Product Details

The MAX2870ETJ+ is a 23.5MHz to 6000MHz fractional/ integer-N synthesizer/VCO in 32 pin TQFN package. This high performance ultra wideband phase locked loop (PLL) with integrated voltage control oscillator (VCO) is capable of operating in both integer-N and fractional-N modes. The MAX2870ETJ+ is capable of synthesizing frequencies from 23.5MHz to 6GHz while maintaining superior phase noise and spurious performance when combined with an external reference oscillator and loop filter. The ultra wide frequency range is achieved with help of multiple integrated VCOs covering 3000MHz to 6000MHz and output dividers ranging from 1 to 128. The device also provides dual differential output drivers which can be independently programmable to deliver -4dBm to +5dBm output power. Both outputs can be muted by either software or hardware control. The MAX2870ETJ+ is used in test and measurement, satellite communications and PMAR/LMAR/public safety radio.


  • Supply voltage range is 3V to 3.6V
  • Operating temperature range from -40°C to 85°C
  • Manual or automatic VCO selection
  • Output binary buffers/dividers for extended frequency range
  • Wide frequency PLL with integrated VCO simplifies signal chain & improves performance
  • 105MHz in integer-N mode and 50MHz in fractional-N mode
  • Reference frequency up to 200MHz and VCO phase noise of -149dBc/Hz at 5MHz offset (VCO at 3000MHz)
  • Analogue and digital lock detect indicators, hardware and software shutdown control
  • Controlled by 3-wire serial interface and compatible with 1.8V control logic
  • In-band noise floor of -226.4 dBc/Hz and 1/f noise of -116dBc/Hz
