WLAN POWER-DOWN SEQUENCE

TiWi5 TRANSCEIVER MODULE

DATASHEET

Notes:

1. The DC2DC(1.8V) signal can be monitored on BT_FUNC2 Module Pin (#41)

2. DC_REQ and CLK_REQ are internal signals shown for reference only

Figure 4 TiWi5 Module Power-down Sequence Requirements

1. DC_REQ will go low only if WLAN is the only core working. Otherwise if another core is working (e.g

BT) it will stay high.

2. CLK_REQ will go low only if WLAN is the only core working. Otherwise if another core is working and

using the FREF (e.g BT) it will stay high.

3. If WLAN is the only core that is operating, WL_EN must remain de-asserted for at least 64ïsec

before it is re-asserted.
