9FGL0841BKILFT 概覽
The Renesas 9FGL0841BKILFT is an 8-output 3.3V PCIe Gen 1-6 clock generator housed in a 48-pin VFQFPN (6x6 mm) package. It supports 100 Ohm differential impedance HCSL outputs at 100 MHz, with each of the eight differential outputs driven by its own dedicated OE# pin implementing PCIe CLKREQ# functionality. According to Renesas documentation, the device supports PCIe Common Clocked (CC), Separate Reference No Spread (SRNS) and Separate Reference Independent Spread (SRIS) architectures, and offers two programmable spread-spectrum levels in addition to spread-off operation.
A clock generator is a semiconductor device that produces one or more precise reference timing signals used to synchronize data transfers between digital subsystems. Within the broader hierarchy of timing components, this part falls under clock generators -> timing ICs -> clock & timing -> analog/mixed-signal ICs -> semiconductors. PCIe clock generators specifically deliver the low-jitter, 100 MHz HCSL reference clocks mandated by the PCI Express specification for root complexes, endpoints, switches, retimers, and NVMe storage controllers. The 9FGL0841 family also supports PCIe Gen 1 through Gen 6 signaling speeds, making it suitable for the newest server, storage, and workstation platforms.
Key specifications include 3.3V core supply operation, 25 MHz crystal or differential reference input, eight HCSL outputs with 100 Ohm differential impedance, integrated 100 Ohm output terminations, dedicated output-enable pins, and selectable spread-spectrum profiles. Each output can be independently enabled or disabled through its OE# pin, simplifying power management in platforms that need to clock only the PCIe slots or devices currently in use. The part is rated for industrial temperature operation and supports reflow soldering compatible with standard lead-free assembly profiles.
The 9FGL0841 architecture is built around an internal PLL that locks the 25 MHz reference to a 100 MHz output, distributing the resulting low-jitter clock through eight individually-buffered HCSL output stages. Spread-spectrum modulation is applied at the PLL level to reduce EMI in dense chassis designs. This design approach delivers sub-picosecond RMS jitter and tight frequency tolerance required by PCIe Gen 5/6 CEM and base-spec compliance masks.
Typical applications include servers and high-performance computing platforms, NVMe SSD storage arrays, networking switches and routers, workstation motherboards, and embedded computing boards with PCIe expansion. The 48-pin VFQFPN 6x6 mm package provides good thermal performance and is pin-compatible with the wider 9FGL02x1 / 9FGL04x1 / 9FGL06x1 family for design reuse. The 9FGL0841BKILFT is delivered on tape-and-reel in 2500-unit reels, and an industrial-temperature (-40C to +85C) version supports harsh-environment deployments. Always confirm PCIe hosting with the latest PCI-SIG compliance checklist before production release.
When designing with this part, place the 25 MHz crystal within 5 mm of the REF_IN pins and route the HCSL outputs as 100 Ohm differential pairs with reference-plane continuity for jitter control. Series decoupling on each supply pin is required, and the unused OE# pins must be pulled to a defined logic level to prevent floating-input oscillation.

主要差異化特點
- Eight independently controlled HCSL outputs in a compact 48-VFQFPN 6x6 mm (對比9FGL0451CKILF (4-output version))
- Pin-compatible upgrade path to PCIe Gen 6 jitter margin (對比9FGL0851BKILFT)
- Supports CC, SRNS, and SRIS reference architectures in one device (對比Generic PCIe clock generators)
設計說明
Route each HCSL output as a 100 Ohm differential pair with continuous reference plane below the trace. Keep trace length matching within 5 mils (0.13 mm) between the positive and negative legs of each pair to preserve duty cycle. Series-resistor placement right at the driver pin (typically 33 Ohm each leg) helps damp reflections and meets PCIe base-spec impedance profiles.
Decouple each VDD pin with a 0.1 uF X7R ceramic capacitor placed within 2 mm of the pin, plus a bulk 10 uF tantalum or ceramic capacitor on the 3.3V rail. Separate analog and digital ground planes are not required for this device but keep the exposed thermal pad soldered to a continuous ground pour for thermal dissipation.
Always tie unused OE# pins to a defined logic level (either pulled high through 10 kOhm or left to the platform controller) - floating OE# inputs can cause output oscillation and excess power consumption. When spread spectrum is enabled, disable it for PCIe compliance testing where a pure tone is required for accurate jitter decomposition.
