The LMK00308SQE/NOPB from Texas Instruments is a high-performance, 3.1-GHz differential fanout buffer designed for low-jitter clock and data distribution. It offers level translation capabilities and is suitable for demanding timing applications.
This device features a 3:1 input multiplexer that accepts universal inputs up to 3.1 GHz, including LVPECL, LVDS, CML, SSTL, HSTL, HCSL, or single-ended clocks, as well as a crystal input for 10 to 40 MHz crystals. The output stage is divided into two banks, each with 4 differential outputs, which can be independently configured as LVPECL, LVDS, or HCSL drivers, or disabled. An additional LVCMOS output with a synchronous enable input is also provided for runt-pulse-free operation.
The LMK00308SQE/NOPB operates with a core supply voltage of 3.3 V ±5% and features three independent output supply voltages (3.3 V/2.5 V ±5%). It is specified for an industrial temperature range of -40°C to +85°C. The component is housed in a 40-lead WQFN package measuring 6 mm × 6 mm.
Key electrical specifications include an additive RMS jitter of 51 fs (typ), output skew of 50 ps, and high PSRR values. The buffer is ideal for applications requiring precise clock distribution and signal integrity in high-frequency systems.
