概要
説明
The 9ZXL0451E is a second-generation enhanced performance DB800ZL derivative for PCIe Gen 4 and 5 applications. In fanout (bypass) mode, it is DB2000Q compatible. A fixed external feedback in zero-delay buffers (ZDB) mode maintains low drift for critical QPI/UPI.
特長
- LP-HCSL outputs eliminate 16 resistors; save 32mm2 of area
- PCIe Gen 1–5 compliance
- 4 OE# pins; SMBus control also available
- 3 selectable SMBus addresses
- 2 selectable ZDB bandwidths; minimizes jitter peaking in cascaded PLL topologies
- Hardware/SMBus control of ZDB bandwidth and fanout modes
- Spread spectrum compatible
- 100MHz ZDB mode
- 5mm × 5mm 32-VFQFPN package; small board footprint

Introducing Renesas’ enhanced PCIe clock buffer family. These PCIe Gen5 clock buffers offer fanout and zero-delay operating modes, supporting both legacy systems and the most complex timing trees within a single device. Unlike many existing solutions, whose performance limitations force their use in fanout buffer mode, these clock buffers meet both PCIe Gen5 and prominent CPU-specific phase jitter requirements in all operating modes. The extremely low 50fs rms PCIe Gen5 additive phase jitter enables multi-level cascading within the strict PCIe Gen5 jitter budget. Renesas’ high-performance oscillators and clock generators provide an ideal clock source for the enhanced PCIe clock buffer family.
