• Manufacturer Part Number: saa4970t
• Description: Economical Video Processing Ic Ecobendic
• Manufacturer: NXP Semiconductors

Philips Semiconductors
D
MUXD/MUXE are filled with current counter values of
CNT_F/CNT_D (horizontal and vertical display position)
by a positive edge of VI2 or using the ‘SAMPLE AQUI and
DISPL’ register. Thus, it is possible to detect the location
of VI2 within one line by reading MUXD (CNT_F) after VI2
has occurred.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
Note
1. Charge device model class B: equivalent to discharging a 200 pF capacitor through a 0
