1 / 17 page DATASHEET 6-OUTPUT LOW-POWER HCSL BUFFER FOR PCIE GEN1-2-3 AND QPI 9ZXL0651 IDT® 6-OUTPUT LOW-POWER HCSL BUFFER FOR PCIE GEN1-2-3 AND QPI 1 9ZXL0651 REV C 040115 General Description The 9ZXL0651 is a low-power 6-output differential buffer that meets all the performance requirements of the Intel DB1200Z specification. It consumes 50% less power than standard HCSL devices and has internal terminations to allow direct connection to 85 ohm transmission lines. The 9ZXL0651 is backwards compatible to PCIe Gen1 and Gen2 and QPI 6.4GT/s specifications. A fixed, internal feedback path maintains low drift for critical QPI applications. Recommended Application 6-Output Low-Power HCSL Buffer for PCIe Gen1-2-3 and QPI Output Features • 6 - 0.7V low-power HCSL (LP-HCSL) output pairs w/integrated terminations Features/Benefits • Low-Power-HCSL outputs w/Zo = 85; save power and board space - no termination resistors required. Ideal for blade servers. • Space-saving 40-pin VFQFPN package • Fixed feedback path for 0ps input-to-output delay • 6 OE# pins; Hardware control of each output • PLL or bypass mode; PLL can dejitter incoming clock • Selectable PLL bandwidth; minimizes jitter peaking in downstream PLL's • Spread Spectrum Compatible; tracks spreading input clock for low EMI Key Specifications • Cycle-to-cycle jitter <50ps • Output-to-output skew <65 ps • Input-to-output delay variation <50ps • PCIe Gen3 phase jitter <1.0ps RMS • QPI 9.6GT/s 12UI phase jitter <0.2ps RMS Block Diagram Logic DIF(5:0) HIBW_BYPM_LOBW# SMBDAT SMBCLK CKPWRGD/PD# Z-PLL (SS Compatible) DFB_OUT_NC DIF_IN DIF_IN# OE(5:0)# |
