LMX2571 command sequence after POR

Gk 110

Hello to whom it may concern,

When we program R0 with RESET=1,how long should we wait until send next command?
After program R0 with RESET=1,should we wait tEWH + tCES?

I want to know latency time until next command after program R0 with RESET=1.

Best regards,

Hi Ito-san,

The device has built-in POR circuitry, so when it is power up, it will reset itself. Reset means restore every register to its silicon default value. The time taken to complete a reset is super fast, in nano-second range.

Similarly, when you do a software reset, the same action will perform and the same amount of time is required.
