The LDO_EN input level must be kept the same as VDDIO voltage level. After initial power-on, the LDO_EN signal can be held low to turn off the SV615XP or pulsed low to induce a subsequent reset. After LDO_EN is assert and host starts the power-on sequence of the SV615XP. From that point, the typical SV615XP power-on sequence is H158A-S shown below:

1. Within 1.3 millisecond, the internal power-on reset (POR) will be done. And host could download firmware code of DPLL setting if the crystal is not default setting, 26MHz. The internal running clock is crystal frequency. 2. After 100us of DPLL settling time, host could set internal clock to full speed and finish all the downloading of firmware code. FN-LINK TECHNOLOGY LIMITED 10 Proprietary & Confidential Information H158A-S The SV615XP LDO_EN pin can be used to completely reset the entire chip. After this signal has been de-asserted, the SV615XP is in off mode waits for host communication. Until then, the MAC, BB, and SOC blocks are powered off and all modules are held in reset. Once the host has initiated communication, the SV615XP turns on its crystal and later on DPLL. After all clocks are stable and running, the resets to all blocks are automatically de-asserted.
