Features 30 fs additive jitter (100 Hz to 20 MHz) Dual clock inputs Programmable output channels (0 to 1600 MHz) External synchronization Pin compatible family of clocking devices 3.15 to 3.45 V operation Package: 48 pin LLP (7.0 x 7.0 x 0.8 mm) Device LVDS Outputs LVPECL Outputs LMK01000 3 5 LMK01010 8 0 LMK01020 0 8 Description The LMK01000 family provides an easy way to divide and distribute high performance clock signals throughout the system. These devices provide best-in-class noise performance and are designed to be pin-to-pin and footprint compatible with LMK03000/LMK02000 family of precision clock conditioners. The LMK01000 family features two programmable clock inputs (CLKin0 and CLKin1) that allow the user to dynamically switch between different clock domains. 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*).

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
