Description for the LMK04906

The LMK04906 is the industry’s highest performance clock jitter attenuator with superior clock jitter cleaning, generation, and distribution with advanced features to meet high performance timing application needs.

The LMK04906 accepts 3 clock inputs ranging from 1 kHz to 500 MHz and generates 6 unique clock output frequencies ranging from 284 kHz to 2.6 GHz. The LMK04906 can also buffer a crystal or VCXO to generate a 7th unique clock frequency.

The device provides virtually all frequency translation combinations required for SONET, Ethernet, Fibre Channel and multi-mode Wireless Base Stations.

The LMK04906 input clock frequency and clock multiplication ratio are programmable through a SPI interface.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
