LMK01010 Datasheet | National Semiconductor

Description 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 patible 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. 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) - - - - - LMK01000: 3 LVDS outputs (CLKout0 - CLKout2) + 5 LVPECL outputs (CLKout3 - CLKout7) - LMK01010: 8 LVDS outputs - LMK01020: 8 LVPECL outputs - Channel divider values of 1, 2 to 510 (even divides) - Programmable output skew control External synchronization Pin patible family of clocking devices 3.15 to 3.45 V operation Package: 48 pin LLP (7.0 x 7.0 x 0.8 mm) Target Applications - - - - - - High performance Clock Distribution Wireless Infrastructure Medical Imaging Wired munications Test and Measurement Military / Aerospace System Diagram TRI-STATE® is a registered trademark of National Semiconductor Corporation. © 2008 National Semiconductor Corporation .national.
