Broadcom’s product portfolio serves multiple applications within seven primary target markets: data center, networking, software, broadband, wireless, storage. Tier one handset manufactures are announcing products this week at the Mobile World Congress that include the BCM with product. This IC Review report provides a technical snapshot of the device including: A device summary table – Photographs of the top and bottom of the package.

Welcome to our Store. Table 4 describes the power-control hand-shake signals used with the UART interface. The accelerators implement the following cipher algorithms: Characteristics of the gSPI mode include: Introduction to Microcontroller World.

Bluetooth messages porduct sent in packets. The last clock edge of the fixed delay word can be used to represent the first bit of the following data word. Channel quality driven data rate and packet type selection?

Automatic frequency detection for standard crystal and TCXO values? Programmable independent basic service set IBSS or infrastructure basic service set functionality? This layer consists of the command controller produt takes commands from the software, and other controllers that are activated or configured by the command controller, to perform the bdief control tasks.

FM Transceiver Subsystem, on page Ramp down the output audio signal toward zero this is the method used in current Bluetooth headsets.


This allows a user to share his or her music or any audio stream with a friend. Ltd WB42 Product Specification Information in this document, including URL references, is producf to change without notice. The recommended configuration for the crystal oscillator including all external components is shown in Figure 5.

Example Soft Mute Characteristic For example, for the 2. On power-up, the PHY performs a full suite of calibration to correct for IQ mismatch and local oscillator leakage. The PHY carrier sense has been tuned to provide high-throughput for Active mode — All components in the BCM are powered up and fully functional with active carrier sensing and frame transmission and receiving.

IC Review of the Broadcom BCM4330 802.11n WiFi / Bluetooth / FM Radio

The PSM uses the channel access information from the IFS module to schedule a queue from which the next frame is transmitted. For a comprehensive list of acronyms and other terms used in Broadcom documents, go to: Consult the reference schematics for the latest configuration.

When the BCM is prodyct on from this state, it is the same as a normal power-up and the device does not contain any information about its state from before it was powered down. Enables the use of Bluetooth technology in a much more secure environment.

The transmit and receive sections include all on-chip filtering, mixing, and gain control functions. All regulators are powered down only when both resets are asserted. Prodhct using a 3 V device in a 5 V system, the user must consider: Signal from the host to the BCM indicating that the host requires attention. When this pin is low, the WLAN section is in reset.


Enable pin allows to reach. System-on-chip is an integrated circuit More information.

Broadcom – WikiDevi

For a clock reference other than If the power supply to this buffer is always on even in sleep modethe clock buffer is always on, thereby ensuring a constant input impedance in all states of the device. Although the document is marked with the name Broadcom, the prkduct that originally developed the specification, Cypress will continue to More information. Integrated CMOS power amplifiers with internal power-detectors and closed-loop power control can deliver greater than 18 dBm of linear output power in 2.

FM mono-stereo blend and switch, and soft mute support? No user interaction is required during normal operation or during manufacturing to provide the optimal performance. Fibocom offers this information. Supports configurable active edge for shifting? Functional Block Diagram, on page 1.

PLL Controlled More information. The interframe spacing timers are triggered by the cessation of channel activity on the medium, as indicated by the PHY.
