9FGV0841

8-Output Very Low-Power PCIe Gen1–4 Clock Generator with Zo = 100ohms 9FGV0841 Datasheet Description The 9FGV0841 is a member of IDT's SOC-friendly 1.8V very low-power PCIe clock family. It has integrated output terminations providing Zo = 100Ω for direction connection to 100Ω transmission lines. The device has 8 output enables for clock management, 2 different spread spectrum levels in addition to spread off, and 2 selectable SMBus addresses. Typical Applications ▪ PCIe Gen1–4 clock generation for Riser Cards ▪ Storage ▪ Networking ▪ JBOD ▪ Communications ▪ Access Points Output Features ▪ Eight 100MHz Low-Power HCSL (LP-HCSL) DIF pairs with Zo = 100Ω ▪ One 1.8V LVCMOS REF output with Wake-On-LAN (WOL) support Key Specifications ▪ DIF cycle-to-cycle jitter < 50ps ▪ DIF output-to-output skew < 50ps ▪ DIF phase jitter is PCIe Gen1–4 compliant ▪ REF phase jitter is < 1.5ps RMS Features ▪ Direct connection to 100Ω transmission lines; saves 32 resistors compared to standard PCIe devices ▪ 62mW typical power consumption; reduced thermal concerns ▪ Outputs can optionally be supplied from any voltage between 1.05V and 1.8V; maximum power savings ▪ OE# pins; support DIF power management ▪ LP-HCSL differential clock outputs; reduced power and board space ▪ Programmable slew rate for each output; allows tuning for various line lengths ▪ Programmable output amplitude; allows tuning for various application environments ▪ DIF outputs blocked until PLL is locked; clean system start-up ▪ ...
