BCM4319XKUBGT Datasheet, PDF (26/84 Pages) Cypress Semiconductor – Single-Chip IEEE 802.11™ a/b/g/n MAC/Baseband/ Radio with Integrated SDIO and USB Interfaces

BCM4319 Preliminary Data Sheet
Bluetooth Coexistence Interface
Bluetooth Coexistence Interface
A 4-wire handshake interface is provided to enable signaling between the device and an external colocated
wireless device, such as Bluetooth GPS, WiMax or UWB, to manage wireless medium sharing for optimum
performance. The IEEE 802.15.2 coexistence schemes can be supported.
The following signals are provided:
• BTCX_STATUS
• BTCX_RF_ACTIVE
• BTCX_FREQ
• BTCX_TXCONF
JTAG Interface
The BCM4319 supports the IEEE 1149.1 JTAG boundary scan standard for testing the device packaging and
PCB during manufacturing. It is also an essential interface for Broadcom to run characterization tests and it is
highly recommended to provide access to these pins on all pcb designs.
