Low Phase-Noise, Low-Power
Programmable PhiClock™
Generators
9FGV1001C / 9FGV1005C
Datasheet
Description
Features
▪ 1.8V to 3.3V power supplies
The 9FGV1001C / 9FGV1005C are members of the Renesas
PhiClock™ programmable clock generator family. The devices are
optimized for low phase noise in non-spread spectrum
applications such as Ethernet or PCI Express. Four user-defined
configurations may be selected via two hardware select pins or
two I2C bits, allowing easy software selection of the desired
configuration.
▪ Individual 1.8V to 3.3V VDDO for each output pair
▪ Supports HCSL, LVDS and LVCMOS I/O standards
▪ HCSL utilizes Renesas’ LP-HCSL technology for improved
performance, lower power and higher integration:
• Programmable output impedance of 85Ω or 100Ω
▪ Supports LVPECL and CML logic with easy AC coupling. See
application note AN-891 for alternate terminations
Typical Applications
▪ On-board OTP supports up to 4 complete configurations
▪ Configuration selected via strapping pins or I2C
▪ Internal crystal load capacitors
▪ High-performance Computing (HPC)
▪ Enterprise Storage including eSSDs
▪ 10G / 25G / 100G Ethernet
▪ Data Center Accelerators
▪ < 125mW at 1.8V, LP-HCSL outputs at 100MHz (9FGV1001C)
▪ < 100mW at 1.8V, LP-HCSL outputs at 100MHz (9FGV1005C)
▪ 4 programmable I2C addresses: D0, D2, D4, D6
▪ Multiple XO replacement
PCIe Clocking Architectures
▪ Common Clocked (CC)
▪ Easily configured with Renesas Timing Commander™ software
or Web Configuration tool
▪ 4 × 4 mm 24-VFQFPN and 24-LGA packages (9FGV1001)
▪ 3 × 3 mm 16-LGA package (9FGV1005)
▪ Integrated crystal option available
▪ Independent Reference without spread spectrum (SRnS)
Output Features
▪ 9FGV1001: 4 programmable output pairs plus 2 REF outputs
▪ 9FGV1005: 2 programmable output pairs plus 1 REF output
▪ 1 integer output frequency per configuration
▪ 1MHz–325MHz differential outputs
Key Specifications
