The PI6C4853111FAEX is one of the latest clock/timing products released by Integrated Device Technology, Inc. (IDT). It is a low-skew, low-jitter clock buffer capable of producing six different outputs that are user-selectable between either 3.3V LVCMOS, 2.5V LVCMOS, LVDS, or HCSL standards. The PI6C4853111FAEX is, like the majority of IDT’s clock/timing products, a low-power, wide operating temperature range device, capable of operating from -40 to 85 degrees Celsius.

The PI6C4853111FAEX finds itself most applicable in network routers and data centers running in high-density configurations. Many of these applications require the generation of several different clock frequencies and references, typically at high intensities, with very low propagation delays. With the PI6C4853111FAEX, these high-speed clocks can be accurately generated, as the device is designed to keep jitter values low when output skew is also low. System engineers can also make advantage of an extremely compact form factor that allows many devices to be placed in close proximity without interfering with one another.

The PI6C4853111FAEX has three main components that are responsible for its clock buffer functionality: a clock input receiver, a clock generator, and a set of drivers. The input receiver takes in a differential clock signal, either LVPECL, LVDS or HCSL, which is then sampled by an on-chip PLL within the clock generator block. The output of the PLL is digitized, and the resulting output frequencies are filtered through a set of Clock Generators that generate precise references in the desiredLVCMOS, LVDS or HCSL form. Finally, the drivers take these references and convert them into new signals that can be used to drive other clocks. The entire process occurs in parallel, allowing for a wide range of clock frequencies to be generated, with minimal delay and minimal jitter between output signals.

The PI6C4853111FAEX is an ideal solution for many clock/timing applications that require differential clock signals to be generated or distributed with low output skew and low jitter. Not only is the device capable of producing multiple references in different standards, its low power consumption, wide operating temperature range, and small form factor make it an attractive option for system engineers in high density network and data center design.
