1 / 18 page DATASHEET 12-OUTPUT LOW POWER DIFFERENTIAL BUFFER FOR PCIE GEN3 AND QPI 9ZXL1230 IDT® 12-OUTPUT LOW POWER DIFFERENTIAL BUFFER FOR PCIE GEN3 AND QPI 1 9ZXL1230 REV B 041112 General Description The 9ZXL1230 is a small-footprint, low power 12-output differential buffer that meets all the performance requirements of the Intel DB1900Z specification. It is pin compatible to the 9ZX21200. The 9ZXL1230 is backwards compatible to PCIe Gen2 and QPI 6.4GT/s specifications. A fixed, internal feedback path maintains low drift for critical QPI applications. Recommended Application 12-output Low Power PCIe Gen3/QPI differential buffer for Romley Output Features • 12 - 0.7V low-power HCSL-compatible output pairs Features/Benefits • Low-power push-pull outputs; Save power and board space - no Rp • Pin compatible to 9ZX21200; easy path to >50% power savings • Space-saving 56-pin QFN package • Fixed feedback path for 0ps input-to-output delay • 9 Selectable SMBus Addresses; Mulitple devices can share the same SMBus Segment • 4 OE# pins; Hardware control of four outputs, other outputs free run • PLL or bypass mode; PLL can dejitter incoming clock • 100MHz or 133MHz PLL mode operation; supports PCIe and QPI applications • 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(11:0) HIBW_BYPM_LOBW# SMBDAT SMBCLK CKPWRGD/PD# SMB_A0_tri SMB_A1_tri 100M_133M# Z-PLL (SS Compatible) DFB_OUT_NC DIF_IN DIF_IN# OE(8,6,4,2)# |
