QAM Cable TV Demodulator - STV0279E - STMicroelectronics

STMicroelectronics announced the STV0279E High Performance QAM Cable TV Demodulator (QAM stand for Quadrature Amplitude Modulation). It adds new features to the widely-used STV0279D to deliver much higher  performance improvements and reducing Bill of Materials list.

The STV0279E inherits all the functionality of the STV0279D and add new features such as four I2C for PVR applications and TSMF to support the Japanese market.

STV0279E enables manufacturers to produce lower cost STB (set-top boxes) solutions with more robust performance, by using a lower cost tuner and other circuits. BOM cost is further reduced by the on-chip 12-bit ADC and the adjacent channels filter.

An extended complex equaliser now provides a total of approximately 100 Feed Forward and Feed Backward taps to allow correction of strong and long echoes.A dedicated phase noise cancellation block has also been introduced, In addition, a FEC (Forward Error Correction) block covering ITU-T annex A and C provides a serial or parallel bit stream. The STV0297E interfaces directly to any MPEG 2/4 decoder.

Its small footprint, low power consumption and outstanding performance, coupled with the ability to reduce the cost of other system components, make the

The price of STV0279E is $3.00 in 10K units.
