Other Parts Discussed in Thread: LMK05028
After reconfiguring the LMK05028 device using the I2C interface the datasheet section 9.5.5 says
5. Write 1b to R12[7] to assert soft-reset. This does not reset register values.
6. Write 1b to R12[7]) to begin normal device operation (starting with VCO calibration and PLL start-up).
This does not seem to work for me. If I write R12[6] (SYNC_SW) to 1 then clear it instead, it works some of the time. By some of the time I mean when reading R13 it returns 0x0 (passing) Other times it returns 0x4.
If I run through the entire configuration sequence twice and set and clear R12[6] instead of R12[7] configuration seems to pass consistently. Is this the expected behavior? Is the documentation correct?
Tanks,
Jim
