DESCRIPTION
The STB6100 ASIC is a highly integrated, low-cost
direct conversion (zero IF) tuner IC for DVB-S2
broadcast satellite applications.
This device includes an LNA, down-converting
mixers, baseband low-pass filters, gain control,
on-chip VCO and a low noise PLL. Its wide gain
control range is well suited for low symbol rate
applications.
The STB6100 is controlled by a simple two wire
interface and has been designed to minimize the
external bill of materials to reduce manufacturing
costs and to simplify the board layout. The
reduced component count ensures greater system
reliability
satisfaction.
The DVB-S2 standard increases the capacity of
satellite broadcasts by as much as 30%, so
enabling the effective deployment of high data rate
applications such as high definition TV and
broadband internet.
