LMK00301SQE

The LMK00301SQE from Texas Instruments is a high-performance differential fanout buffer and level translator designed for clock distribution applications. It features 11 outputs and supports universal inputs up to 3.1 GHz, accepting various logic levels including LVPECL, LVDS, CML, SSTL, HSTL, HCSL, and single-ended clocks. A dedicated crystal input supports 10 MHz to 40 MHz crystals.

The device offers two banks of five differential outputs each, configurable to LVPECL, LVDS, HCSL, or Hi-Z. It boasts ultra-low additive RMS jitter, with typical values of 51 fs (12 kHz to 20 MHz). The frequency range extends up to 3100 MHz for LVPECL outputs. High PSRR performance is also a key feature, with -65 dBc for LVPECL and -76 dBc for LVDS at 156.25 MHz.

Operating with a core supply voltage of 3.3V and independent output supply voltages of 2.5V or 3.3V, the LMK00301SQE is suitable for a wide range of system designs. It operates within an industrial temperature range of -40°C to +85°C. The component is housed in a 48-lead WQFN package with dimensions of 7 mm x 7 mm, designed for surface mounting.

Key electrical specifications include an output skew of 50 ps and support for various input and output types such as CML, HCSL, HSTL, LVCMOS, LVDS, LVPECL, LVTTL, SSTL, and XTAL inputs, and HCSL, LVDS, LVPECL outputs. The device also includes a synchronous enable input for LVCMOS outputs and pin-controlled configuration.
