Description
LMK00301SQ/NOPB is TI’s low-jitter clock buffer with a built‑in jitter cleaner and 4-output fanout in a lead-free (NOPB) package (SQ package type). It cleans a reference clock and distributes a low-skew clock to multiple loads, making it ideal for synchronizing FPGAs, ASICs, and processors.
Key points:
- One reference, four outputs (low skew across outputs)
- Built‑in jitter cleaner to improve timing budgets
- Packaged in the SQ/lead-free package (LMK00301SQ) with NOPB suffix
- Used for clock distribution in high-speed digital systems; supports common clock formats and power-down/enable features
- Read the datasheet for exact input freq range, jitter specs, drive capabilities, and pinout
For a detailed introduction and design guidelines, refer to TI’s LMK00301 data sheet and application notes.
