TSW4806EVM
An option for installing a commercial-quality voltage-controlled crystal oscillator (VCXO) is available on the
board, providing a known reference point for evaluation of the device performance in dual-PLL mode.
The board features an on-board 10-MHz reference oscillator for internal clock reference and output
reference source.
The on-board EEPROM programs the LMK04806, providing several factory pre-programmed settings. The
board provides 491.52-, 245.76-, 122.88-, and 61.44-MHz outputs after power up (or after pushing the
RESET button) if the four dip switches are in their default
0000 position (all up). A software GUI is also
provided allowing custom configuration of the LMK04806.
The EVM supports any of the four devices offered in the LMK04800 family with the default device being
the LMK04806.
