Product details
Overview
9DBV0531AKLF from Renesas Electronics is a 5-output, 1.8V low-power PCIe Gen5 fanout buffer with LP-HCSL outputs, PCIe Gen5 Common Clocked additive phase jitter <40fs RMS, output-to-output skew <50ps, and 1MHz–200MHz operating frequency-designed for high-speed clock distribution in server and NVMe storage systems.
For engineers reviewing the 9DBV0531AKLF datasheet, 9DBV0531AKLF pinout, 9DBV0531AKLF application, or 9DBV0531AKLF equivalent, this device supports SMBus-configurable slew rate per output, spread-spectrum compatibility, individual OE# control per output, and operates across –40°C to +85°C industrial temperature range.
Technical Context
The 9DBV0531AKLF implements a zero-delay fanout architecture with differential input (CLK_IN/CLK_IN#) and five true/complementary LP-HCSL outputs (DIF0–DIF4), each with dedicated active-low enable (vOE0#–vOE4#). It supports both Common Clocked (CC) and Independent Reference (IR) PCIe clocking architectures, including SRIS/SRNS modes.
Its internal SMBus engine enables dynamic configuration-including per-output slew rate, differential amplitude, and address selection via vSADR_tri-while retaining full functionality without SMBus interface, thanks to factory-default settings and 3.3V-tolerant SCLK_3.3/SDATA_3.3 pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCIe Gen5 CC additive phase jitter | <40fs RMS - meets stringent Gen5 timing margin requirements for high-reliability server backplanes |
| 12kHz–20MHz additive phase jitter | 165fs RMS at 156.25MHz - ensures low-noise operation in wideband clock synthesis paths |
| Output-to-output skew | <50ps - maintains tight inter-channel alignment critical for multi-lane PCIe/NVMe timing |
| Operating frequency range | 1MHz–200MHz - supports PCIe Gen1–Gen5 reference clocks (100MHz, 125MHz, 156.25MHz) and custom frequencies |
| Power consumption | 41mW typical - enables dense clock tree deployment with minimal thermal impact |
| Supply voltages | VDDDIG1.8 = 1.7–1.9V; VDDO1.8 = 1.7–1.9V; VDDR1.8 = 1.7–1.9V - single-rail 1.8V system integration with analog/digital isolation |
| Temperature range | –40°C to +85°C - qualified for industrial-grade embedded and datacenter applications |
Pinout & Package
9DBV0531AKLF is housed in a 32-pin 5×5 mm VFQFPN package (0.5mm pitch) with exposed pad (EPAD) connected to GND. Pin count and layout match the 9DBV05x1 family variant; no NC pins present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| vOE0#–vOE4# | Active-low output enable inputs | Individually gate DIF0–DIF4 outputs; internal 120kΩ pull-downs allow default-disable or SMBus-controlled power gating |
| DIF0–DIF4 / DIF0#–DIF4# | Differential LP-HCSL clock outputs | 33Ω source-terminated outputs compatible with 85Ω and 100Ω trace impedances; eliminate external termination resistors |
| CLK_IN / CLK_IN# | Differential reference clock input | Accepts LVDS/LP-HCSL-level input; 300mV min differential swing; 150–900mV crossover voltage tolerance |
| SCLK_3.3 / SDATA_3.3 | SMBus interface | 3.3V-tolerant, 400kHz max; enables runtime configuration of slew rate, amplitude, and address without interrupting clock operation |
| ^CKPWRGD_PD# | Power-good / power-down control | Pull-up enabled; low asserts hardware power-down mode (<0.1mA total IDD), high enables clock distribution |
| vSADR_tri | SMBus address select | Tri-level latched input (GND/VDD/float) sets one of three SMBus addresses (0x5A/0x5B/0x5C) |
Key Features
| Feature | Design Value |
|---|---|
| 5-channel LP-HCSL outputs with integrated 33Ω termination | Eliminates four external resistors per output pair, reducing BOM count and PCB area in 85Ω/100Ω systems |
| Per-output slew rate control via SMBus | Optimizes EMI and signal integrity independently per lane-critical for mixed-sensitivity PCIe/NVMe subsystems |
| Individual OE# pins with internal pull-downs | Enables PCIe CLKREQ#-compatible dynamic output gating per slot or device, reducing system-level idle power |
| Factory-default configuration | Operates immediately on power-up without SMBus initialization-simplifies boot sequence and firmware dependencies |
| Spread-spectrum compatibility | Supports SRIS/SRNS modes per PCIe specification, enabling jitter reduction in noise-sensitive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCIe fanout buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT8T49N242A | 8-output, 2.5V core; supports JESD204B; higher power (85mW); no per-output OE# | Better suited for JESD204B + PCIe hybrid systems; lacks PCIe CLKREQ# support | Choose when JESD204B co-clocking is required and 5-output count is not limiting |
| Si53306-A01AGM | 6-output, 1.8V; integrated PLL; higher additive jitter (65fs RMS Gen5); SMBus-only control | Provides frequency translation; less suitable for pure fanout due to added jitter and no OE# pins | Choose when clock multiplication or re-timing is needed alongside fanout |
Compared with IDT8T49N242A and Si53306-A01AGM, the 9DBV0531AKLF delivers lower Gen5 jitter, per-output power gating, and true 1.8V operation-making it optimal for PCIe-optimized, power-constrained, and thermally demanding server/storage designs.

FAQ
What is the maximum operating frequency supported by the 9DBV0531AKLF?
The 9DBV0531AKLF supports an operating frequency range from 1MHz to 200MHz, covering all standard PCIe reference frequencies-including 100MHz (Gen1/Gen2), 125MHz (Gen3), and 156.25MHz (Gen4/Gen5)-as well as custom clock rates used in networking and storage applications.
Does the 9DBV0531AKLF require an SMBus interface to function?
No, the 9DBV0531AKLF operates fully with factory-default settings and does not require SMBus communication. The SMBus interface (SCLK_3.3/SDATA_3.3) is optional and used only for advanced configuration such as per-output slew rate adjustment or address selection-enabling plug-and-play deployment in time-critical systems.
How does the 9DBV0531AKLF support PCIe CLKREQ# functionality?
The 9DBV0531AKLF supports PCIe CLKREQ# through its five dedicated active-low output enable pins (vOE0#–vOE4#), each controlling one LP-HCSL output pair. When asserted low, the corresponding DIFx/DIFx# output is disabled-matching the CLKREQ# handshake protocol used by PCIe slots to request clock gating during low-power states.
What package type and dimensions does the 9DBV0531AKLF use?
The 9DBV0531AKLF uses a 32-pin Very Thin Quad Flat No-lead (VFQFPN) package measuring 5mm × 5mm with 0.5mm pitch and an exposed thermal pad (EPAD) that must be soldered to ground. This compact, thermally efficient package is optimized for high-density server and storage PCB layouts.
Is the 9DBV0531AKLF compliant with PCIe Gen5 timing specifications?
Yes, the 9DBV0531AKLF meets PCIe Gen5 Common Clocked architecture requirements with additive phase jitter <40fs RMS and output-to-output skew <50ps-verified per PCI Express Base Specification 7.0, Revision 1.0 test methodology using 12kHz–20MHz brick-wall filtering and real-time oscilloscope measurement.
