Digital TV chipset avoids IF headaches

Philips Semiconductor has introduced a three chip set for digital satellite broadcast set-top boxes which does away with the need for separate intermediate frequency components.
The new chip set lowers manufacturing costs by as much as 30 per cent by eliminating components such as an IF oscillator, IF mixer and SAW filter.
Philippe Hermant, product marketing manager, at Philips Semiconductors said that without the need for IF components, the chipset offered an important breakthrough in eliminating “one of the most problematic areas for design engineers.”
The three chips are the TDA8060, the TDA8043 and the TSA5512. Philips is offering a reference design to help customers design systems with the chips.
