TA1375FG
Single Conversion Tuner for Digital TV / CATV
The TA1375FG is a tuner IC for for Digital TV and CATV applications
that integrates a PLL block and mixer, oscillator, IF amplifier and IF
GCA on a single chip.
This oscillator and PLL circuits are low phase noise.
The control data of the PLL block conforms to I²C-bus formats.
