Renesas Electronics Corporation Application Specific Clock/Timing 9DB433AGLFT

The 9DB433AGLFT is a four-output differential buffer designed for PCIe Gen1 to Gen3 applications, ensuring zero delay and fanout capabilities. It is compatible with differential SRC output pairs from clock generators such as the IDT 932S421 or 932SQ420. The device features output cycle-to-cycle jitter of less than 50 ps and output-to-output skew of less than 50 ps, with phase jitter for PCIe Gen3 specified at less than 1.0 ps rms. This buffer supports multiple operational modes, including PLL and bypass modes, with selectable bandwidth options to minimize jitter peaking in downstream PLLs. It operates at frequencies ranging from 50 to 110 MHz in PLL mode and 5 to 166 MHz in bypass mode. The device includes a SMBus interface for address selection and control, allowing multiple devices to share the same SMBus segment. Additionally, it features power management capabilities, supporting undriven differential outputs in power-down mode. The 9DB433AGLFT is packaged in a 28-pin TSSOP and is RoHS compliant, making it suitable for a variety of applications requiring reliable clock distribution with low electromagnetic interference (EMI).
