9ZXL0651E Datasheet | Renesas

Description The 9ZXL04x1E/9ZXL06x1E/9ZXL08x1E/9ZXL12x1E family of Zero-Delay/Fanout Buffers (ZDB, FOB) are 2nd-generation enhanced performance buffers for PCIe and CPU applications. The family meets all published QPI/UPI, DB2000Q and PCIe Gen1- 5 jitter specifications. Devices range from 4 to 12 outputs, with each output having an OE# pin to support the PCIe CLKREQ# function for low power states. All devices meet DB2000Q, DB1200ZL and DB800ZL jitter and skew requirements. PCIe Clocking Architectures - mon Clocked (CC) - Independent Reference (IR) with and without spread spectrum (SRIS, SRNS) Key Specifications - Fanout Buffer Mode additive phase jitter: - PCIe Gen5 CC < 24fs RMS - DB2000Q additive jitter < 40fs RMS - QPI/UPI 11.4GB/s < 40fs RMS - IF-UPI additive jitter < 70fs RMS - ZDB Mode phase jitter: - PCIe Gen5 CC < 22fs RMS - QPI/UPI 11.4GB/s < 120fs RMS - IF-UPI additive jitter < 130fs RMS - Cycle-to-cycle jitter < 50ps - Output-to-output skew < 50 ps Block Diagram VDDR VDDA Features - 4- 12 Low-power HCSL (LP-HCSL) outputs - Integrated terminations eliminate up to 4 resistors per output pair - Dedicated OE# pins support PCIe CLKREQ# function - Up to 9 selectable SMBus addresses (9ZXL12) - Selectable PLL bandwidths minimizes jitter peaking in cascaded PLL topologies - Hardware/SMBus control of ZDB and FOB modes - Spread-spectrum patible - 1- 400MHz FOB operation (all devices) - 100MHz and 133.33MHz ZDB mode (9ZXL12, 9ZXL08) - 100MHz ZDB mode (9ZXL06, 9ZXL04) - -40°C to +85°C operating temperature range (all devices) - -40°C to +105°C operating temperature range (9ZXL08) - Package information: see Ordering Information for details Applications - Servers/High-performance puting - n VME Storage - Networking -...
