9FGL PCI Express (PCIe) clock generator with integrated device technology (IDT). The 9FGL clock generator family is a member of the IDT 3.3V low-power PCIe family, and supports a common clock (CC) with or without spread spectrum and an independent reference-less-extension (SRnS) PCIe clock architecture. The company stated that the 9FGL06 and 9FGL08 generators operate at 120mW and 130mW respectively, and are the lowest power 3.3V PCIe clock generators currently available, thereby eliminating heat dissipation issues in high-performance consumer devices.
The device generates low-power HCSL differential clock outputs in 6-output (9FGL06) or 8-output (9FGL08). All 9FGL clock generators support two different spreading levels and a shutdown function (0% spread spectrum). Connects directly to a transmission line and a small 40-pin 5mm x 5mm (9DFGL06) or 48-pin 6mm x 6mm (9FGL08) VFQFPN package reduces required board space and BOM costs.
The 9FGL0641 and 9FGL0651 devices include default configurations, and the 9FGL06P1 and 9FGL08P1 devices can be programmed using a user-defined power-up default SMBus configuration. These SMBus optional features allow optimization options including controlling input polarity, controlling input pull-up / pull-down, slew rate of each output, differential output amplitude, 33 ohm, 85 ohm or 100 ohm output impedance and spreading amount per output.
Applications include computing systems, network systems, industrial applications, and data communications applications.
