MC88PL117FN中文资料摩托罗拉数据手册PDF规格书

The MC88PL117 utilizes proven phase–locked loop clock driver technology to create a large fan–out, multiple frequency and phase, low skew clock driver. The 88PL117 provides the clock frequencies necessary to drive systems using the PowerPC™ 601 microprocessor and the Pentium™ microprocessor (see applications section for details).

• Clock Driver for PowerPC 601 and Pentium Microprocessors

• 14 programmable outputs

• Maximum output–to–output skew of 500ps for a single frequency

• Maximum output–to–output skew of 500ps for multiple frequencies

• fMAX of 2X_Q = 120MHz

• One output with programmable phase capability

• ±36mA DC current outputs drive 50Ω transmission lines

• A lock indicator output (LOCK) goes high when steady–state phase–lock is achieved

• OE/MR 3–state control

• Dedicated feedback output

• Two selectable clock inputs

• PLL enable pin for testability

• Dynamic Switch Between SYNC Inputs
