TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC

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.
