TV on a chip

Broadcom has developed a single-chip that enables manufacturers to develop complete lines of televisions that support analog, high definition, standard definition and digital cable television programming.

Broadcom’s BCM3560 is a single-chip that enables consumer electronics manufacturers to develop complete lines of televisions that support analog, high definition (HD), standard definition (SD) and digital cable television programming.

The new device also integrates video processing functions that allow manufacturers to customize the video output from the device to support multiple television displays, including liquid crystal displays (LCD), plasma displays, cathode ray tube (CRT) displays and projection technology.

The chip integrates both analog and digital receivers compliant with NTSC, ATSC and digital cable television standards. Advanced features in the BCM3560 include picture-in-picture (PIP) capabilities, an advanced 3-D comb Y/C standard separation circuit, a multi-field de-interlace circuit, proprietary picture improvement functions, digital and analog video output interfaces and video scalars.

The architecture of the integrated ATSC receiver enables the chip to acquire, track and demodulate signals in the presence of interference or a wide range of varying multi-path channel conditions that experience the presence of noise. The on-chip IF demodulator, dual NTSC analog video decoders, broadcast stereo decoder and HD decoder enable the televisions to support a multitude of picture-in-picture combinations.

The BCM3560 includes support for analog input signals from external devices such as DVD players and VCRs with its ability to directly accept composite, S-video and high definition (HD) as well as standard definition (SD) component input signals. Digital input signals are supported by an integrated high-definition multimedia interface (HDMI) receiver, providing an industry standard interface to other high definition video and multi-channel audio consumer electronics.

The new device also has analog-to-digital and digital-to-analog converters, interfaces for memory, smart cards, a high-speed interface supporting a high-speed 1394 connection, integrated memory and a flexible interface bus to support additional connectivity, including wireless and USB connections.

Broadcom has also made available a set of reference software and development tools to complement the BCM3560 to minimize system development time and complexity for television manufacturers.

The device will be sampling to early access customers during the first quarter of 2005. Pricing is available upon request.
