Features

  • PCIe Gen 1–6 CC-compliant
  • Supports PCIe SRIS and SRNS clocking
  • Integrated terminations for 100Ω and 85Ω systems save 4 resistors per output
  • Pin-selectable SRnS 0%, CC 0%, and CC/SRIS -0.5% spread
  • SMBus-selectable CC/SRIS -0.25% spread
  • One 3.3V LVCMOS REF output with Wake-On-LAN (WOL) support

  • Space saving 5mm × 5mm 32-VFQFPN

Description

The 9FGL0441/51 devices are 4-output 3.3V PCIe Gen 1–6 clock generators. Each output has a dedicated OE# pin supporting PCIe CLKREQ# functionality. Two different spread spectrum levels, in addition to spread off, are supported. The 9FGL0441/51 supports PCIe Gen 1–6 Common Clocked architectures (CC), PCIe Separate Reference no Spread (SRNS), and Separate Reference Independent Spread (SRIS) clocking architectures.

  1. 9FGL04 SSC

    Hi, I am using 9FGL0451DKILFT, I want to know how is SSC being configured? based on table 1. if I connect SS_EN_tri pin to VDD/2. does this mean B1[4:3] is 10 and spread is 0 without any SW config? based on table 21, B1 ...

  2. VersaClock6E IDT5P49V60A000NLG2 blank samples: step by step calibration procedure via I2C on customer target board

    Dear Renesas Timing Team, receiving VersaClock6E IDT5P49V60A000NLG2 blank samples and would like to program them on their target board by using I2C. Refering to the RegProgGuide “Power UP Behaviour..”, point 3 where point 4 doesn’t says much about calibration procedure in case if the samples are not factory programmed ...
