TDA4670 Product details

Description

TDA4670 The TDA4670 delays the luminance signal and improves colour-difference signal transients.Additionally, the luminance signal can be improved by peaking and noise reduction (coring).MAX.8.8 52 1130 640 V UNIT mA ns mV V V dB dB °C ORDERING INFORMATION TYPE NUMBER TDA4670 PACKAGE NAME DIP18 DESCRIPTION plastic dual in-line package; 18 leads (300 mil) VERSION SOT102-1 1996 Dec 11 2 Product speciﬁcation TDA4670 Fig.1 Block diagram.handbook, full pagewidth 1996 Dec 11 100 nF 2

Features

Luminance signal delay from 20 to 1100 ns (minimum step 45 ns).
Luminance signal peaking with selectable symmetrical overshoots.
2.6 or 5 MHz peaking centre frequency and selectable degree of peaking (.
3, 0, +3 and +6 dB).
Selectable noise reduction by coring.
Handles negative and positive colour-difference signals.
Selectable Colour Transient Improvement (CTI) to decrease the colour-difference signal transient times to those of the.
