The 9FGV1008 is a member of Renesas' PhiClock™ programmable clock generator family. The 9FGV1008 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

  • PCIe Gen1–4 compliant
  • 224fs RMS typical phase jitter at 156.25MHz (12kHz–20MHz)
  • 2 programmable output pairs plus 1 LVCMOS REF output
  • 1 integer and 1 fractional or spread-spectrum output per configuration
  • 1MHz–325MHz integer outputs (LVDS or LP-HCSL)
  • 1MHz–200MHz integer outputs (LVCMOS)
  • 1.8V to 3.3V core VDD
  • Individual 1.8V to 3.3V VDDO for each programmable output pair
  • Supports HCSL, LVDS and LVCMOS I/O standards
  • Supports AC-coupled LVPECL and CML logic – see AN-891
  • 3 × 3 mm 16-LGA packages with 50MHz integrated crystal option
  • Supported by Timing Commander™ software
