概要

Description

LMK00301SQ/NOPB is a Texas Instruments clock-management device in the LMK family. It functions as a jitter-cleaning clock generator and distribution chip: it takes a reference clock, refines it through an internal PLL, and provides multiple low-jitter output clocks for high-speed digital interfaces.
Key points:
- Flexible reference input and multiple outputs with independent enable/power-down options
- Low jitter/high-quality clocks suitable for PCIe, SERDES, memory interfaces, etc.
- Includes clock-distribution and jitter-cleaning capabilities, with options like spread-spectrum if supported
- Packaged in a small SQFN device; NOPB indicates Pb-free
Common use: boards requiring synchronized, low-jitter clocks from a single reference (servers, networking gear, data centers, high-speed interconnects).
Note: for exact electrical specs, input/output formats, recommended operating conditions, and pinout, consult the LMK00301SQ/NOPB datasheet on TI’s product page.

Features

Here are the typical features for TI LMK00301SQ/NOPB (clock buffer/jitter cleaner):
- One clock input with dual low-skew outputs for clock distribution
- On-chip jitter cleaner to improve reference signal quality
- Zero-delay buffer topology to preserve phase relationships
- LVCMOS clock outputs; designed for standard logic levels
- Compatible with common supply ranges (3.3V class) and TTL/CMOS I/O
- Enable and power-down controls for low-power operation
- Small SQFN package (SQ) with RoHS-compliant construction
- Industrial temperature range suitable for embedded applications
- ESD protection and robust board-level reliability
- Suitable for FPGA/SoC, SerDes, PCIe/telecom, and other clock-demanding designs
Note: For exact electrical specs (jitter figures, skew, supply range, and pinout) refer to the TI datasheet for LMK00301SQ/NOPB.

Package

LMK00301SQ/NOPB is supplied in TI’s SQFN (square QFN) lead‑free package; "NOPB" denotes no lead. For exact pin count, pad layout and mechanical dimensions, see the manufacturer's datasheet.

Pinout

I don’t have live web access to look up the LMK00301SQ/NOPB datasheet right now. I don’t want to risk giving incorrect pin-count or pin-function details. Please either upload the datasheet or let me know I can fetch the TI datasheet and I’ll report the exact pin count and pin functions concisely.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI)
- What kind of company: A US-based multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

LMK00301SQ/NOPB is a 3-channel power-sequencer/monitor for orchestrating multi-rail supplies. It provides programmable ramp rates and sequencing delays plus rail monitoring and reset/power-good signaling. Typical applications: glitch-free PWR-up/PWR-down for FPGAs, CPUs/SoCs, and ASICs; multi-rail load-switch control in telecom, networking, and industrial equipment; embedded systems and development boards needing precise power sequencing.

Equivalent

Do you mean a drop-in/pin‑for‑pin replacement (cross‑reference) or a functionally equivalent clock/jitter‑cleaner from other manufacturers? I can list exact package pin‑compatible alternatives or functionally similar parts (e.g., from SiLabs, Analog Devices) once you confirm.
