The 9FGV1008B is a member of IDT's PhiClock™ programmable clock generator family. The 9FGV1008B provides one integer frequency, one copy of a fractional or spread spectrum output frequency, and one copy of the crystal reference input. Two select pins allow for hardware selection of the desired configuration, or two I2C bits allow easy software selection of the desired configuration. The user may configure any one of the four OTP configurations as the default when operating in I2C mode. Four unique I2C addresses are available, allowing easy I2C access to multiple components.

Features

  • 1.8V–3.3V core VDD and VDDREF
  • Individual 1.8V–3.3V VDDO for each output pair
  • Supports HCSL, LVDS and LVCMOS I/O standards
  • HCSL utilizes IDT's LP-HCSL technology for improved performance, lower power and higher integration:
    • Programmable output impedance of 85Ω or 100Ω
  • On-board OTP supports up to 4 complete configurations
  • Configuration selected via strapping pins or I2C
  • Internal crystal load capacitors
  • < 135mW at 1.8V with outputs running at 100MHz (LP-HCSL)
  • 4 programmable I2C addresses: D0, D2, D4, D6
  • Supports LVPECL and CML logic with easy AC coupling – see AN-891 for alternate terminations
  • Supported by IDT Timing Commander™ software
  • Integrated 50MHz crystal option on 9FGV1008Q5
  • Programmable spread spectrum modulation frequency and amount
