9DBV0941
9DBV0941 is 5 to 9-Output 1.8V Low-Power Buffers manufactured by Renesas.
- Part of the 9DBV0531 comparator family.
- Part of the 9DBV0531 comparator family.
Description
The 9DBV05x1/9DBV07x1/9DBV09x1 fanout buffers are low-power, high-performance fanout buffers in Renesas' Full Featured PCIe family. The buffers have 5, 7 or 9 outputs with each output having an OE# to support the PCIe CLKREQ# function. The devices have 3 selectable SMBus addresses.
PCIe Clocking Architectures
- mon Clocked (CC)
- Independent Reference (IR) with and without spread spectrum
(SRIS, SRNS)
Typical Applications
- Servers/High-performance puting
- n VME Storage
- Networking
- Accelerators
- Industrial Control
Key Specifications
- PCIe Gen5 CC additive phase jitter <40fs RMS
- 12k Hz- 20MHz additive phase jitter = 165fs RMS at 156.25MHz
(typical)
- Output-to-output skew < 50ps
- Power consumption as low as 41m W (typical)
- 1MHz to 200MHz operating frequency
Features
- 5- 9 Low-Power HCSL (LP-HCSL) outputs
- 100Ω outputs eliminate 4 resistors per output pair
(9DBVxx41)
- 33Ω outputs eliminate 2 resistors per output pair allowing use in both 85Ω and 100Ω systems (9DBVxx31)
- Easy AC-coupling to other logic families, see application note AN-891
- Spread spectrum patible
- OE# pins support PCIe CLKREQ# function
- 3 selectable SMBus addresses
- 3.3V tolerant SMBus interface
- SMBus-selectable features allow optimization to customer requirements:
- Individual slew rate control for each output
- Differential output amplitude
- Device contains default configuration; SMBus interface not required for device operation
- -40°C to +85°C operating temperature range
- Packages: See Ordering Information for more details
