Other Parts Discussed in Thread: WL1835MOD, TWL1200, WL1271, WL1835

Attached schematic for the verification. pls. confirm the connection diagram.

Pls. confirm where to connect the pin name CLK_REQ(A) and CLK_REQ(B) in the sch, is it connected to WL1835MOD.if yes at what pin.

TWL1200 ZCQ package is used there are two pins left CLK_REQ(A) and CLK_REQ(B),

In TWL1200, a clock path (CLK_REQ_B-> CLK_REQ_A) from periperal (B side) to contorller (A side) is provieded. In some application, the path is used ( TWL12000+WL1271). In your application, these two pins can be floating.

Thanks,

what about the rest of the interface signal connection, is it correct one.

specially connection like UART_1_TX_1V8 and UART_1_RX_1V8 goes to WLAN module

I check WL1835 datasheet. BT_HCI_TX_1V8 is output signal and BT_HCI_RX_1V8 is input signal. As for TWL1200, BT_UART_RX(B) is output signal and BT_UART_TX(B) is input signal. Thus, BT_HCI_TX_1V8 should be connected to BT_UART_TX(B) and BT_HCI_RX_1V8 should connect to BT_UART_RX(B). Since I am not familiar with WL1835, please double check with engineer who is support WiLink™ WiFi + Bluetooth Forum.

Thanks
