Block Diagram PI6CG18xQ and PI6CB18xQ

Our broad portfolio of automotive-compliant PCIe clock generators and buffers provides various options to cater to your design needs. This includes our latest AEC-Q100 qualified, PCIe 6.0 clock generators—which provide low-power, integrated resistors, and wettable flank/sidewalled QFN packages optimized for the automotive industry.

The PI6CG33xQ is a family of AEC-Q100 Grade 2 qualified, low-power, PCIe 6.0/5.0/4.0 clock generators with 2, 4, 6, and 8 outputs.

The PI6CG18xQ is a family of AEC-Q100 Grade 2 qualified, low-power, PCIe 4.0 clock generators with 2, 4, and 8 outputs. These devices use a 25MHz crystal or CMOS reference input to generate multiple 100MHz HCSL outputs with on-chip terminations. The on-chip termination saves four external resistors for each output, as well as board space. An additional buffered reference output is provided to serve as a low-noise and synchronous reference. The PI6CB184Q is an AEC-Q100 Grade 2 qualified, low-power, PCIe 4.0 clock buffer with 4 outputs. This buffer includes on-chip termination and individual output, enabling improved power management.

Both families of clock generators and buffers are packaged in specially designed wettable/sidewalled QFN packages to enable Automated Visual Inspection and testing in an automotive production environment.
