概述

Description

LMK05028RGCR is TI’s clock conditioner/fanout buffer (LMK05028 family). It takes a reference clock and provides multiple low-jitter outputs, using an integrated PLL/jitter-cleaning stage. Key points:
- Purpose: jitter-cleaned clock distribution to multiple devices (FPGA/SoC, SerDes, PHYs, etc.).
- Features (typical): multi-output clock generation, holdover, optional spread-spectrum, and controllable output formats.
- Outputs: configurable fanout to several outputs with low jitter.
- Packaging: RGCR denotes a specific RoHS-compliant package variant; check the datasheet for exact pinout and electrical specs.
Note: Always consult the LMK05028 datasheet for detailed electrical characteristics, input ranges, output formats (LVDS/LVCMOS/LVPECL, etc.), and packaging details.

Package

LMK05028RGCR uses a 28-pin QFN package (QFN-28) with an exposed pad.

Pinout

- Pin count: 28 pins (package: 28-pin QFN)
- Function: Low-jitter clock conditioner and fan-out buffer (clock generator/distributor) with I2C control; cleans a reference clock and generates multiple synchronized downstream clock outputs for SERDES/FPGA/SoC applications.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- About the company: Texas Instruments is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits used in a wide range of electronics.

Application

LMK05028RGCR is a low-jitter clock conditioner and distributor that generates multiple clean, phase-aligned clocks from a single reference. Typical applications: high-speed data/telecom and networking gear (PCIe/SerDes, Ethernet, USB, SATA); FPGA/ASIC designs requiring synchronized clock trees; data centers and servers; RF/microwave test and measurement equipment; and consumer electronics requiring precise timing.
