9DBL0242
9DBL0242 is Zero-Delay/Fanout Buffer manufactured by Renesas.
Description
The 9DBL02x2/9DBL04x2/ 9DBL06x1/9DBL08x1 buffers are low-power, high-performance members of Renesas' full featured PCIe family. The buffers support PCIe Gen1 through Gen5.
PCIe Clocking Architectures
- mon Clocked (CC)
- Independent Reference (IR) with and without spread spectrum
(SRIS, SRNS)
Typical Applications
- PCIe Riser Cards
- n VME Storage
- Networking
- Accelerators
- Industrial Control/Embedded
Features
- 2 to 8 Low-Power HCSL (LP-HCSL) outputs eliminate 4 resistors per output pair
- 9DBLxx4x devices provide integrated 100Ω terminations
- 9DBLxx5x devices provide integrated 85Ω terminations
- See AN-891 for easy coupling to other logic families
- Spread-spectrum patible
- Dedicated OE# pin for each output
- 1MHz to 200MHz operation in fan-out mode
- 3 selectable SMBus addresses
- Extensive SMBus-selectable features allow optimization to customer requirements
- SMBus interface not required for device operation
- -40°C to +85°C operating temperature range
- Space-saving 4 × 4 mm 24-VFQFPN to 6 × 6 mm 48-VFQFPN packages (see Ordering Information table for details)
Key Specifications
- Additive PCIe Gen5 CC jitter < 60fs RMS (fan-out mode)
- PCIe Gen5 CC jitter < 150fs RMS (High-BW ZDB Mode)
