9DBV05x1/9DBV07x1/ 9DBV09x1 5 to 9-Output 1.8V Low-Power Buffers for PCIe Gen15 Datasheet Description Features 59 Low-Power HCSL (LP-HCSL) outputs The 9DBV05x1/9DBV07x1/9DBV09x1 fanout buffers are low-power, high-performance fanout buffers in Renesas Full 100 outputs eliminate 4 resistors per output pair Featured PCIe family. The buffers have 5, 7 or 9 outputs with each (9DBVxx41) output having an OE to support the PCIe CLKREQ function. 33 outputs eliminate 2 resistors per output pair allowing The devices have 3 selectable SMBus addresses. use in both 85 and 100 systems (9DBVxx31) Easy AC-coupling to other logic families, see application note PCIe Clocking Architectures AN-891 Common Clocked (CC) Spread spectrum compatible Independent Reference (IR) with and without spread spectrum OE pins support PCIe CLKREQ function (SRIS, SRNS) 3 selectable SMBus addresses 3.3V tolerant SMBus interface Typical Applications SMBus-selectable features allow optimization to customer Servers/High-performance Computing requirements: nVME Storage Individual slew rate control for each output Networking Differential output amplitude Accelerators Device contains default configuration SMBus interface not Industrial Control required for device operation -40C to +85C operating temperature range Key Specifications Packages: See Ordering Information for more details PCIe Gen5 CC additive phase jitter < 40fs RMS 12kHz20MHz additive phase jitter = 165fs RMS at 156.25MHz (typical) Output-to-output skew < 50ps Power consumption as low as 41mW (typical) 1MHz to 200MHz operating frequency Block Diagram 7 and 9 output parts only VDDDIG1.8 VDDR1.8 VDDIO CLK IN DIFn CLK IN DIFn vSADR tri 5, 7 or 9 SMBus Factory outputs SMBCLK Engine Configuration SMBDAT DIF0 DIF0 CKPWRGD PD n+1 Control Logic vOE n:0 Resistors are integrated on 9DBVxx4x GNDR EPAD/GND GNDDIG 2020 Renesas Electronics Corporation 1 June 30, 20209DBV05x1/9DBV07x1/9DBV09x1 Datasheet Contents Description 1 PCIe Clocking Architectures . 1 Typical Applications . 1 Key Specifications 1 Features 1 Block Diagram . 1 Pin Assignments 3 9DBV05x1 Pin Assignment . 3 9DBV07x1 Pin Assignment . 4 9DBV09x1 Pin Assignment . 5 Pin Descriptions 6 Absolute Maximum Ratings . 8 Thermal Characteristics 8 Electrical Characteristics . 9 Power Management 14 Test Loads . 14 General SMBus Serial Interface Information . 16 How to Write . 16 How to Read . 16 Package Outline Drawings . 21 Marking Diagrams . 21 9DBV05x1 . 21 9DBV07x1 . 22 9DBV09x1 . 22 Ordering Information . 23 Revision History . 24 2020 Renesas Electronics Corporation 2 June 30, 2020
