National Semiconductor LMK01010
The LMK01000/LMK01010/LMK01020 family provides an easy way to divide and distribute high performance clock signals throughout the system. These devices provide best-inclass noise performance and are designed to be pin-to-pin and footprint compatible with LMK03000/LMK02000 family of precision clock conditioners. The LMK01000/LMK01010/LMK01020 family features two programmable clock inputs (CLKin0 and CLKin1) that allow the user to dynamically switch between different clock domains.GENERAL DESCRIPTION
Each device features 8 clock outputs with independently programmable dividers and delay adjustments. The outputs of the device can be easily synchronized by an external pin (SYNC*).FEATURES
● 30 fs additive jitter (100 Hz to 20 MHz)● Dual clock inputs
● Programmable output channels (0 to 1600 MHz)
