3-Channel AD Converter
The TC90A58F is a 3-channel AD converter for video
applications which incorporates a clamp circuit.
The 10-bit converter can be used as either an 8-bit 3-channel
AD converter or as a 10-bit 2-channel AD converter.
Main Functions and Features
· 3-channel, 8-bit AD converter (input amplitude: 1.32 Vp-p)
· Y, Cb and Cr or R, G and B inputs.
· Pedestal clamp (Y or RGB: 16 LSB (in 8-bit conversion), Cb,
Cr: 128 LSB (in 8-bit conversion)
· Switchable between external input or internal generation of
clamp pulse
Weight: g (typ.)
· Operates at 30 MHz maximum.
· Digital filter
(Y: 6 MHz, Cb, Cr: 2.8 MHz/6 MHz)
· 10-bit output (only for 2-channel ADC)
· Horizontal PLL (HPLL)
· ITU-R601 and ITU-R656 formats supported
(For ITU-R656, HD and VD must be input.)
· Y-signal delay circuit (delay amount can be set from 0 to 14 clocks, in units of clocks)
· I²C bus control
· Built-in color bar generator
