Description

The AK1590 is a 60MHz to 1000MHz delta-sigma modulated fractional-N PLL frequency synthesizer.
The AK1590 consists of an 18-bit delta-sigma modulation circuit, low-noise phase frequency comparator, high-precision charge pump, reference divider, dual modulus prescaler (P / P + 1), and frequency offset adjustment circuit.

Key Features

  • 18-bit delta-sigma modulation circuit type PLL
  • Low current consumption. / Low noise.
