Description
The U6220B is a single cip PLL designed for TV and
VCR receiver systems. It consists of a divide-by-8
prescaler (up to 1.3 GHz) with an integrated preamplifier,
a 15bit programmable divider, a crystal oscillator and a
B B B ^{reference divider with three selectable divider ratios}
( 256 / 512 / 1024), a phase/frequency detector
together with a charge-pump, which drives the tuning
amplifier. Only one external transistor is required for
varactor line driving. The device can be controlled via a
I²C bus format or 3-wire bus format. It detects
automatically which bus format has been received,
therefore there is no need for a bus selection pin. In I²C
bus mode the device has four programmable addresses,
programmed by applying a specific input voltage to the
address select input, enabling the use of up to four
synthesizers in a system. The same pin serves in 3-wire
bus mode as the enable signal input. Five open collector
outputs for band switching functions are included, four of
them are capable of sinking at least 10 mA and the VHF
L/H output can sink 30 mA. One of these open collector
outputs serves as a lock-signal output in the 3-wire bus
mode. The MS output is provided to control directly a
mixer-oscillator IC according to the band switching
information.
