Overview
Description
The RC19020 is a 20-output PCIe Gen6 buffer that is backward compatible with earlier PCIe generations. The RC19020 provides ultra-low additive jitter and reduced in-to-out delay performance for better design margin and incorporates several features for easier and more robust design.
RC19020 is also pin-compatible to DB2000Q/DB2000QL plus adding Loss-Of-Signal (LOS) indication and an SBI_OUT pin for multiple clock chip daisy-chain.
Features
- LP-HCSL outputs eliminate up to 80 terminated resistors
- PCIe Gen 1–6 compliance
- Drive both source-terminated and double-terminated loads
- Selectable output slew rate via SMBus
- Supports 85Ω output impedance
- Open-drain LOS (Loss-Of-Signal) indication output
- Power down tolerance (PDT)
- Flexible startup sequencing (FSS)
- Automatic clock parking (ACP)
- Dedicated OE# pins to control group output
- 4-wire Side-Band interface and device daisy-chaining
- SMBus write protection features with 9 selectable addresses
- 6mm x 6mm 80-GQFN and 10mm x 10mm 72-VFQFPN packages
