PRODUCTION DATA
A common automotive PCIe application, such as ADAS (Advanced Driver Assistance Systems), requires several clocks and timing sources to drive the building blocks of the system. In a common ADAS system, the clock is distributed to an SoC, PCIe Switch, WiFi Controller, and Gigabit Ethernet to transmit high-speed video data from the IP-Based Cameras on the vehicle. The LMK00334-Q1 provides an automotive qualified solution that saves cost and space. When transmitting high-speed video data, the additive jitter of the buffer clock may noticeably impact performance. In order to optimize signal speed and cable length, system designs must account for this additive jitter. The LMK00334-Q1 is an ultra-low-jitter PCIe clock buffer suitable for current and future automotive PCIe applications.
