Table 153.  Transmit PLLs in Cyclone® 10 GX Devices
PLL Type Characteristics
Advanced Transmit (ATX) PLL
  • Best jitter performance
  • LC tank based voltage controlled oscillator (VCO)
  • Used for both bonded and non-bonded channel configurations
Fractional PLL (fPLL)
  • Ring oscillator based VCO
  • Supports fractional synthesis mode
  • Used for both bonded and non-bonded channel configurations
Clock Multiplier Unit (CMU) PLL or Channel PLL 27
  • Ring oscillator based VCO
  • Used as an additional clock source for non-bonded applications
27 The CMU PLL or Channel PLL of channel 1 and channel 4 can be used as a transmit PLL or as a clock data recovery (CDR) block. The channel PLL of all other channels (0, 2, 3, and 5) can only be used as a CDR.
