ICS8545-02

LOW SKEW, 1-TO-4 LVCMOS/LVTTL-TO-LVDS FANOUT BUFFER ICS8545-02 Description The ICS8545-02 is a low skew, high performance 1-to-4 LVCMOS/LVTTL-to-LVDS Clock Fanout HiPerClockS™ Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. Utilizing Low Voltage Differential Signaling (LVDS) the ICS8545-02 provides a low power, low noise, solution for distributing clock signals over controlled impedances of 100Ω. The ICS8545-02 accepts an LVCMOS/LVTTL input level and translates it to 3.3V LVDS output levels. Features Four differential LVDS output pairs Two LVCMOS/LVTTL clock inputs to support redundant or selectable frequency fanout applications Maximum output frequency: 350MHz Translates LVCMOS/LVTTL input signals to LVDS levels Output skew: 60ps (maximum) Part-to-part skew: 450ps (maximum) Propagation delay: 1.45ns (maximum) Additive phase jitter, RMS: 0.14ps (typical) Full 3.3Vsupply mode 0°C to 70°C ambient operating temperature Available in both standard (RoHS 5) and lead-free (RoHS 6) packages ICS www.DataSheet4U.com Guaranteed output and part-to-part skew characteristics make the ICS8545-02 ideal for those applications demanding well defined performance and repeatability.
