Description

The 840NT4 is a PLL-based clock generator designed to interface with Freescale B4/T4 Processor systems. The clock generator offers low jitter, low-skew clock outputs, frequency margining (0.025MHz to 0.312MHz step granularity), and spread spectrum clocking that meets the ever-growing demands of Freescale’s next-generation processors.
