Comprehensive range of signal switches, clock generators and clock buffers for PCIe 4.0 applications
The PI3DBS16212 and PI3DBS16412 are 1-20Gbps 2-channel and 4-channel 2:1 differential mux/demux with low loss, reflection, crosstalk and skew. The components flexibility for channels and routing, typical applications include switching high-speed serial signals for 20Gbps Thunderbolt 3; 16Gbps PCIe 4.0 architecture; 10Gbps USB3.1 Gen2; 12Gbps Serial Attached SCSI 3 (SAS3); 8.1Gbps Display Port 4 (DP4); 12Gbps HDMI2.1, and 10Gbps Ethernet standards.
For PCIe 4.0 applications, PI3DBS16212 and PI3DBS16412 offer high signal integrity with a low insertion loss of -1.3dB at 16Gbps. In this application, minimal skew between channels eases the timing budget between nodes, and power dissipation is very low at typically 300µA. The parts use silicon on insulator (SOI) technology and are available in small packages.
The PI6CG18201, PI6CG18401 and PI6CG15401 clock generators provide 1.8V 2/4/8 HCSL outputs and 1.5V 4 HCSL outputs, respectively, and use a proprietary phase-locked loop design to achieve jitter performance of less than 0.5ps. The parts also provide the reference clock for SERDES chipsets supporting the PCIe 4.0 interface. Each output has its own enable with programmable slew rate and amplitude. On-chip termination resistors are incorporated.
PI6CB18200, PI6CB18401, PI6CB18601 and PI6CB18801 are PCIe 4.0 2/4/6/8 HCSL output clock buffers fanned-out from a reference input. The slew rate and amplitude of each output is programmable and there are individual output enables for better power management. Additive jitter for the clock buffers is less than 0.05ps.
