LMK03318RHSR Description

Short technical summary and product information.

The LMK03318RHSR from Texas Instruments is an ultra-low-noise, high-performance clock generator designed for demanding applications. It incorporates a single fractional-N frequency synthesizer with an integrated VCO, providing flexible clock distribution and fanout capabilities.

 

Key electrical specifications include ultra-low jitter of 100-fs RMS typical for frequencies above 100 MHz and robust power supply noise rejection (PSNR) of -80 dBc. The device supports dual inputs with automatic or manual selection, including a crystal input range of 10 to 52 MHz and an external input range of 1 to 300 MHz. It can generate up to 8 outputs, configurable as AC-LVPECL, AC-LVDS, AC-CML, HCSL, or LVCMOS.

 

This clock generator operates with a 3.3-V core supply and offers output supply voltages of 1.8-V, 2.5-V, or 3.3-V. It is designed for an industrial temperature range of -40°C to 85°C. The LMK03318RHSR is available in a 48-WQFN package with surface mount mounting type.

 

Applications for the LMK03318RHSR include switches and routers, network and telecom line cards, servers and storage systems, wireless base stations, PCIe Gen1-4 interfaces, test and measurement equipment, and broadcast infrastructure.
