LVCMOS clock fan-out buffer

www.DataSheet4U.com PCK9446 2.5 V and 3.3 V LVCMOS clock fan-out buffer Rev. 01 — 10 April 2006 Product data sheet 1. General description The PCK9446 is a 2.5 V and 3.3 V compatible 1 : 10 clock distribution buffer designed for low-voltage mid-range to high-performance telecom, networking and computing applications. Both 3.3 V, 2.5 V and dual supply voltages are supported for mixed-voltage applications. The PCK9446 offers 10 low skew outputs and 2 selectable inputs for clock redundancy. The outputs are configurable and support 1 : 1 and 1 : 2 output to input frequency ratios. The PCK9446 is specified for the extended temperature range of −40 °C to +85 °C. The PCK9446 is a full static design supporting clock frequencies up to 250 MHz. The signals are generated and retimed on-chip to ensure minimal skew between the three output banks. Two independent LVCMOS compatible clock inputs are available. This feature supports redundant clock sources or the addition of a test clock into the system design. Each of the three output banks can be individually supplied by 2.5 V or 3.3 V supporting mixed voltage applications. The FSELx pins choose between division of the input reference frequency by one or two. The frequency divider can be set individually for each of the three output banks. The PCK9446 can be reset and the outputs are disabled by deasserting the MR/OE pin (logic HIGH state). Asserting OE will enable the outputs. All inputs accept LVCMOS signals while the outputs provide LVCMO.
