8-Output DB800ZL Derivative for

PCIe Gen1–4 and UPI with Write

Lock

9ZXL0832E / 9ZXL0852E

Datasheet

Description

Features

▪ SMBus write lock feature; increases system security

The 9ZXL0832E / 9ZXL0852E are second-generation, enhanced

performance DB800ZL differential buffers. The parts are

pin-compatible to the 9ZXL0831A and 9ZXL0851A while offering a

much improved phase jitter performance. A fixed external feedback

maintains low drift for critical QPI/UPI applications. The 9ZXL0832E

and 9ZXL0852E have an SMBus Write Lockout pin for increased

device and system security.

▪ LP-HCSL outputs; eliminate 16 resistors, save 27mm²of area

(0832E)

▪ LP-HCSL outputs with 85Ω Zout; eliminate 32 resistors, save

64mm²of area (0852E)

▪ 8 OE# pins; hardware control of each output

▪ Selectable PLL BW; minimizes jitter peaking in cascaded PLL

topologies

PCIe Clocking Architectures

Supported

▪ Common Clocked (CC)

▪ Hardware/SMBus control of PLL bandwidth and bypass; change

mode without power cycle

▪ Spread spectrum compatible; tracks spreading input clock for EMI

▪ Independent Reference (IR) with and without spread spectrum

reduction

▪ 100MHz & 133.33MHz PLL Mode; UPI and legacy QPI support

▪ 6 × 6 mm 48-VFQFPN package; small board footprint

Typical Application

▪ Servers

▪ Storage

Key Specifications

▪ Networking

▪ SSDs

▪ Output-to-output skew < 50ps

▪ Input-to-output delay: Fixed at 0ps

▪ Input-to-output delay variation < 50ps

▪ Phase jitter: PCIe Gen4 < 0.5ps rms

▪ Phase jitter: QPI/UPI > = 9.6GB/s < 0.2ps rms

▪ Phase jitter: IF-UPI < 1.0ps rms

Output Features

▪ 8 Low-Power (LP) HCSL output pairs (0832E)

▪ 8 Low-Power (LP) HCSL output pairs with 85Ω Zout (0852E)
