TA1360AFG
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA1360AFG
YCbCr/YPbPr Signal and Sync Processor for Digital TV, Progressive Scan TV and Double
Scan TV
The TA1360AFG integrates an analog component signal
(YCbCr/YPbPr) processor and sync processor in a 80-pin QFP
plastic package. The IC is ideal for digital TVs, progressive TVs,
and double scan TVs.
The luminance block and the color difference block incorporate
the high performance signal processing circuits. The sync
processor block supports 525I/60, 625I/50, 525P/60, 625P/50,
1125I/50, 1125I/60, 750P/60, (750P/50), PAL100 Hz, NTSC120 Hz,
and SVGA/60(VESA).
The TA1360AFG incorporates the I2C bus. The device can
control various functions via the bus line.
Weight: 1.6 g (typ.)
