3-GHz, 10-output differential fanout buffer / level translator

The LMK00301 is a 3GHz, 10-output

differential fanout buffer intended for high-frequency, low-jitter clock and 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 five 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. The LMK00301 operates from a 3.3V core supply

and three independent 3.3V or 2.5V output supplies.

The LMK00301 provides high

performance, versatility, and power efficiency, making the device designed for

replacing fixed-output buffer devices while increasing timing margin in the system.

The LMK00301 offers a design spin, the LMK00301A, that does not have power supply

sequencing requirements between the core and output supply domains.
