Description for the LMK00301
The LMK00301 is a 3-GHz, 10-output differential fanout buffer intended forhigh-frequency, low-jitter clock/data distribution and level translation. The input clock can beselected from two universal inputs or one crystal input. The selected input clock is distributed totwo banks of 5 differential outputs and one LVCMOS output. Both differential output banks can beindependently configured as LVPECL, LVDS, or HCSL drivers, or disabled. The LVCMOS output has asynchronous enable input for runt-pulse-free operation when enabled or disabled. The LMK00301operates from a 3.3 V core supply and 3 independent 3.3 V/2.5 V output supplies.
The LMK00301 provides high performance, versatility, and power efficiency, making itideal for replacing fixed-output buffer devices while increasing timing margin in thesystem.
The LMK00301A is nearly identical to the LMK00301, but does not have power supplysequencing requirements between the core and output supply domains.
NEW - You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.
A custom reel
is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.
Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.TI often ships
devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
