RENESAS RC19204AGNL#BB0 Clock Multiplier, 2.97 V to 3.63 V, 4 Outputs, QFN-28, -40°C to 105°C

RC192xx is a PCIe gen5/6 2-input clock mux family with loss-of-signal indication. The RC192xx are ultra-high performance clock muxes supporting PCIe Gen5 and Gen6. They provide a Loss-Of-Signal (LOS) output for system monitoring and redundancy. The devices also incorporate Power Down Tolerance (PDT), Flexible Power Sequencing (FPS) and Automatic Clock Parking (ACP) features to insure good behaviour under abnormal system conditions. They can drive both source-terminated and double-terminated loads up to 400MHz. The CLKIN inputs also support either HCSL or LVDS signalling levels, making the devices ideal for LVDS to HCSL level translation. The excellent phase jitter and PNSR performance make the RC192xx well suited for network applications. It has low additive phase jitter (PCIe Gen5 additive phase jitter: 7fs RMS and PCIe Gen6 additive phase jitter: 4fs RMS). Applications include cloud/high-performance computing, nVME storage, networking, accelerators, computing and industrial.

• 4 PCIe outputs, <1.7ns maximum in-out propagation delay
• DB2000Q additive phase jitter of 9fs RMS
• 2:N or 2 x 1:N/2 modes (N is number of outputs), 85ohm or 100 ohm output impedance
• 4-wire side-band interface, 9 selectable SMBus addresses, SMBus write protection
• Temperature range from -40 to +105?C, 3.3V?10% operation
• Ultra-low additive jitter meets/exceeds PCIe Gen5 design requirements
• Spread-spectrum tolerant, open-drain LOS output
• ACP cleanly parks outputs in low/low state when selected input clock is lost
• Outputs drive both source-terminated and double terminated loads
