Description
The U6225B is a single chip PLL for SAT-TV tuners. It contains on one chip all functions required for PLL control 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.

Features
● 2.9 GHz divide-by-16 prescaler integrated
● Universal bus:
    I2C-bus or 3-wire-bus
    I2C-bus software compatible to U6204B
    3-wire-bus software compatible to U6358B (19 bit)
● I2C-bus mode:
    5 switching outputs (open collector)
    4 addresses selectable at pin 10 for multituner application
● 3-wire-bus mode:
    4 switching outputs (open collector)
    Locksignal output (open collector)
● Low power consumption (typical 5 V / 23 mA)
● Electrostatic protection according to MIL-STD 883

Benefits
● Only one device for 3-wire bus applications and I2C-bus applications necessary (universal bus)
● High input frequency of 2.9 GHz applicable for all TV-satellites
