PLL

The INNOSILICON high performance PLL is a high speed, low jitter frequency synthesizer and developed as an IP block to reduce time to market, risk and cost in the development of Analog Front-End design. It can generate stable high-speed clock from a ultra wide input clock. With excellent supply noise immunity, the PLL is ideal for using in noisy mixed signal SOC environments. This PLL integrates a Phase Frequency Detector (PFD), a Low Pass Filter (LPF), a Voltage Controlled Oscillator and other associated circuit. All fundamental building blocks as well as fully programmable dividers are integrated in the core.

KEY FEATURES:

  • Dual power supply: 1.8V (analog)/0.8V(digital) allows for excellent supply noise rejection
  • Reference clock frequency range from 5MHz to 500MHz
  • PFD frequency range 5MHz to 100MHz
  • VCO frequency can support range from 1GHz to 8GHz
  • Lock detector to indicate frequency locked state

INNOSILICON ADVANTAGES:

  • low power consumption
  • low jitter
  • wide frequency range
  • small area
