Evaluation Board User Guide

The
evaluation software can be used to generate binary
setup files that can be used by EEPROM programmers, such as
those made by BPM Microsystems.
Clicking Generate Binary File from the File menu prompts the
user to enter a file name. The .bin extension is assumed. There
is no facility for loading a .bin file into the software.
The binary file format is such that Byte Offset 0 in the binary
file contains the value for Register 0x000.
CHECKSUM GENERATION
Both 8-bit and 16-bit checksums are supported. The device
checksum is calculated using Address 0x00 through
Address 0x232. The data pattern checksum uses Address 0x00
through Address 0xB03.
The 8-bit checksum is an 8-bit sum of the byte range described
previously, whereas the 16-bit checksum forms a 16-bit word in
which the MSB is the odd register addresses, and the LSB is the
even numbered registers. For example, Register 0x000 and
Register 0x001 are paired together prior to the summation
process.
The checksum values are also stored in the .stp files generated
by the evaluation software.
AVOIDING CHECKSUM MISMATCHES
It is possible to have differences in the setup and binary files
that may cause checksum mismatches. These scenarios are
outlined as follows.
The evaluation software automatically sets the VCO calibration
now bit (Register 0x018, Bit 0) in the .bin file if the PLL is
turned on. If the VCO calibration now bit is not set, the
is unable to lock the PLL after automatically loading the
register values from the EEPROM without further user
intervention. Register 0x018, Bit 0 is not normally set in the
register setup (.stp) file because the user normally initiates VCO
calibration manually while running the evaluation software. To
avoid a checksum mismatch, it is recommended that the user
manually set the VCO calibration now bit in the setup file if the
PLL is enabled.
Register 0x01F is a read-only status register whose value can
change in between the writing of the setup (.stp) file and the
binary (.bin) file. This situation is likely to occur if the reference
input frequency monitors are enabled and the reference inputs
are left floating. To prevent this, the user must avoid leaving the
reference inputs floating, or disconnect the evaluation board
while saving the setup and corresponding binary file.

ESD Caution
ESD (electrostatic discharge) sensitive device
. Charged devices and circuit boards can discharge without detection. Although this product features patented or proprietary protection
circuitry, damage may occur on devices subjected to high energy ESD. Therefore, proper ESD precautions should be taken to avoid performance degradation or loss of functionality.

promptly return the Evaluation Board to ADI. ADDITIONAL RESTRICTIONS. Customer may not disassemble, decompile or reverse engineer chips on the Evaluation Board. Customer shall inform ADI of any
occurred damages or any modifications or alterations it makes to the Evaluation Board, including but not limited to soldering or any other activity that affects the material content of the Evaluation Board.
Modifications to the Evaluation Board must comply with applicable law, including but not limited to the RoHS Directive. TERMINATION. ADI may terminate this Agreement at any time upon giving written notice
to Customer. Customer agrees to return to ADI the Evaluation Board at that time. LIMITATION OF LIABILITY. THE EVALUATION BOARD PROVIDED HEREUNDER IS PROVIDED “AS IS” AND ADI MAKES NO
WARRANTIES OR REPRESENTATIONS OF ANY KIND WITH RESPECT TO IT. ADI SPECIFICALLY DISCLAIMS ANY REPRESENTATIONS, ENDORSEMENTS, GUARANTEES, OR WARRANTIES, EXPRESS OR IMPLIED, RELATED
TO THE EVALUATION BOARD INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTY OF MERCHANTABILITY, TITLE, FITNESS FOR A PARTICULAR PURPOSE OR NONINFRINGEMENT OF INTELLECTUAL
PROPERTY RIGHTS. IN NO EVENT WILL ADI AND ITS LICENSORS BE LIABLE FOR ANY INCIDENTAL, SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES RESULTING FROM CUSTOMER’S POSSESSION OR USE OF
THE EVALUATION BOARD, INCLUDING BUT NOT LIMITED TO LOST PROFITS, DELAY COSTS, LABOR COSTS OR LOSS OF GOODWILL. ADI’S TOTAL LIABILITY FROM ANY AND ALL CAUSES SHALL BE LIMITED TO THE
AMOUNT OF ONE HUNDRED US DOLLARS ($100.00). EXPORT. Customer agrees that it will not directly or indirectly export the Evaluation Board to another country, and that it will comply with all applicable
United States federal laws and regulations relating to exports. GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the substantive laws of the Commonwealth of
Massachusetts (excluding conflict of law rules). Any legal action regarding this Agreement will be heard in the state or federal courts having jurisdiction in Suffolk County, Massachusetts, and Customer hereby
submits to the personal jurisdiction and venue of such courts. The United Nations Convention on Contracts for the International Sale of Goods shall not apply to this Agreement and is expressly disclaimed.
