U6225B
2.9 GHz PLL for SAT TV Receiver with Universal Bus
Description
The U6225B is a single chip PLL for SAT-TV tuners. It
contains on one chip all functions required for PLL con-
trol of a VCO. This IC also contains a high frequency
prescaler and can handle frequencies up to 2.9 GHz.
The U6225B has a fixed reference divider of 512, while
the U6223B has a programmable 256/ 512/ 1024
reference divider.
