June 2005 ASM2I99456 rev 0.2 3.3V/2.5V LVCMOS Clock Fanout Buffer Features ƒ Configurable 10 outputs LVCMOS Clock distribution buffer ƒ Compatible to single, dual and mixed 3.3V/2.5V Voltage supply ƒ Wide range output clock frequency up to 250MHz ƒ Designed for mid-range to high-performance telecom, networking and computer applications ƒ Supports high-performance differential clocking applications ƒ Max. output skew of 200pS (150pS within one bank) ƒ Selectable output configurations per output bank ƒ Tristatable outputs ƒ 32 LQFP and TQFP Packages ƒ Ambient Operating temperature range of -40 to 85°C ƒ Pin and Function compatible to MPC9456 Functional Description The ASM2I99456 is a 2.5V and 3.3V compatible 1:10 clock distribution buffer designed for low-Voltage mid-range to high-performance telecom, networking and computing applications. Both 3.3V, 2.5V and dual supply voltages are supported for mixed-voltage applications. The ASM2I99456 offers 10 low-skew outputs and a differential LVPECL clock input. The outputs are configurable and support 1:1 and 1:2 output to input frequency ratios. The ASM2I99456 is specified for the extended temperature range of –40 to 85°C. The ASM2I99456 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. Each of the three output banks can be individually supplied by 2.5V or 3.3V supporting mixed voltage applications. The FSELx pi...
