Automotive-compliant PCIe 4.0 clocks
Diodes Incorporated has released automotive-compliant PCI Express (PCIe) 4.0 clock generators and buffers with advanced features for demanding automotive applications, including head units, ECUs, ADAS, navigation, telematics, and infotainment.

The PI6CG182Q, PI6CG184Q PI6CG188Q (PCIe 4.0 clock generators with 2, 4 and 8 outputs) and PI6CB184Q (PCIe 4.0 clock buffers with 4 outputs) provide differential low-power, high-speed current steering logic (HCSL) outputs with on-chip termination. They have been designed to generate and distribute a reference clock signal for chipsets employing PCIe Gen 4 interfaces. These devices are all qualified to AEC-Q100 Grade 2, with an operating temperature range of -40°C to +105°C, therefore they are suitable for any automotive PCIe application.

Operating at 1.8V and with integrated on-chip termination at every HCSL output, the devices minimize power consumption and remove the need for external resistors. Each output also features its own enable pin to further improve power management on outputs that are unused.
