S4505

The S4505 has the following features including Provides two Rambus compatible clock outputs from 240 to 310 MHz;Uses low cost 14.318 MHz crystal as reference for 250 MHz output;Low Jitter, <100 ps;Output skew <50ps;45/55% duty cycle;On-chip filter requires no external components;Eight-pin, .150" SOIC;Series resonant input crystal requires no external components.

AMCC's advanced PLL technology allows the S4505 to provide two Rambus-compatible, 250, 267, or 300 MHz clocks from a low cost 14.318 MHz crystal.Other reference crystals can be used to produce other output frequencies within the 240-310 MHz range. An external series resistor allows the output to be matched to the Rambus transmission line im-pedance needed for each application. AMCC utilizes its high speed, low-fitter PLL technology developed for telecom and precision clocking applications to provide outputs which meet the low fitter and symmetrical duty cycle requirements of RAMBUS system clocks.Stresses greater than the absolute maximum ratings may cause permanent damage to the device.Functional operation of the S4505 at these or any other conditions above those indicated under the normal operating conditions is not guaranteed. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The S4505 described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
