General Description
The LMK04906 Evaluation Board simplifies evaluation of the LMK04906B Low-Noise Clock
Jitter Cleaner with Dual Loop PLLs. Texas Instrument‟s
CodeLoader
software can be used to
program the internal registers of the LMK04906B device through the MICROWIRE
TM
interface.
The
CodeLoader
software will run on a Windows 2000 or Windows XP PC and can be
downloaded from

Evaluation Board Kit Contents
The evaluation board kit includes:
(1) LMK04906 Evaluation Board from Table 1
(1) CodeLoader uWire cable (LPT
uWire)
Available LMK04906 Evaluation Boards
The LMK04906 Evaluation Board supports any of the four devices offered in the LMK04906
Family. All evaluation boards use the same PCB layout and bill-of-materials, except for the
corresponding LMK04906B device affixed to the board. A commercial-quality VCXO is also
mounted to the board to provide a known reference point for evaluating device performance and
functionality.
