9ZXL0831E Overview
The 9ZXL0831E / 9ZXL0851E are second-generation enhanced performance DB800ZL differential buffers. The parts are pin-patible upgrades 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.
9ZXL0831E Key Features
- 8 Low-Power (LP) HCSL output pairs (0831E)
- 8 Low-Power (LP) HCSL output pairs with 85Ω Zout (0851E)
- LP-HCSL outputs; eliminate 16 resistors, save 27mm2 of area (0831E)
- LP-HCSL outputs with 85Ω Zout; eliminate 32 resistors, save 64mm2 of area (0851E)
- 8 OE# pins; hardware control of each output
- Selectable PLL BW; minimizes jitter peaking in cascaded PL
