LMK00308SQ Integrated Circuit Chip 3.1GHz 8-Output Differential Clock Buffers WQFN-40

Product Description Of LMK00308SQ

LMK00308SQ is a 3-GHz, 8-output differential fanout buffer intended for high-frequency, low-jitter clock/data distribution and level translation. The input clock can be selected from two universal inputs or one crystal input. The selected input clock is distributed to two banks of 4 differential outputs and one LVCMOS output. Both differential output banks can be independently configured as LVPECL, LVDS, or HCSL drivers, or disabled. The LVCMOS output has a synchronous enable input for runt-pulse-free operation when enabled or disabled.

LMK00308SQ operates from a 3.3 V core supply and 3 independent 3.3 V/2.5 V output supplies. It provides high performance, versatility, and power efficiency, making it ideal for replacing fixed-output buffer devices while increasing timing margin in the system.
