LMK03328RHSR Description

Short technical summary and product information.

The LMK03328RHSR is an ultra-low noise clock generator designed by Texas Instruments. This device features two fractional-N frequency synthesizers with integrated VCOs, providing flexible clock distribution and fan-out capabilities. It offers up to 8 outputs that can be configured as AC-LVPECL, AC-LVDS, AC-CML, HCSL, or LVCMOS.

 

Key electrical specifications include ultra-low jitter of 100fs RMS typical for frequencies above 100MHz and robust supply noise immunity with a PSNR of -80dBc. The device supports dual inputs with automatic or manual selection, including a crystal input range of 10MHz to 52MHz and an external input range of 1MHz to 300MHz. It offers fine frequency margining of ±50ppm typical.

 

The LMK03328RHSR operates with a 3.3V core supply and offers output supply voltages of 1.8V, 2.5V, or 3.3V. It is designed for an industrial temperature range of -40°C to 85°C. The device is available in a 48-WQFN package measuring 7mm x 7mm.

 

This clock generator is suitable for applications such as switches and routers, network and telecom line cards, servers and storage systems, wireless base stations, and test and measurement equipment. Its ultra-low jitter helps reduce bit error rates in high-speed serial links.
