The Texas Instruments LMK03001ISQX/NOPB is a clock conditioner that accepts LVCMOS, LVDS, or LVPECL inputs and delivers up to eight LVDS or LVPECL outputs with a 1:8 fanout ratio. It operates at frequencies up to 1.57 GHz, making it suitable for cleaning up and distributing high-speed clocks in RF and base station timing chains.
No official replacement or successor is listed on the record.
Package and thermal: 48-WFQFN with exposed pad
The package is surface-mount and RoHS-compliant per the NOPB suffix.
Input and output interface flexibility
The device accepts LVCMOS, LVDS, or LVPECL inputs and provides LVDS or LVPECL outputs. All inputs and outputs are differential-capable, which helps maintain signal integrity over long traces or in noisy environments. The 1:8 fanout allows a single clean clock source to drive multiple downstream devices without additional buffering.
