ILA8395N

TECHNICAL DATA SECAM decoder FEATURES Fully integrated filters Alignment free For use with baseband delay ILA8395N GENERAL DESCRIPTION The ILA8395N is a self-calibrating, fully integrated SECAM decoder. The IC should preferably be used in conjunction with the PAL/NTSC decoder ILA8362ANS (TDA8362A) or TDA8366 and with the switched capacitor baseband delay circuit ILA4661 (TDA4661, TDA4660). The IC incorporates HF and LF filters, a demodulator and an identification circuit (luminance is not processed in this IC). The IC needs no adjustments and very few external components are required. A highly stable reference frequency is required for calibration and a two-level sandcastle pulse for blanking and burst gating. 16 QUICK REFERENCE DATA SYMBOL Vp V16(p-p) Tstg Tamb PARAMETER Positive supply voitage; pin 3 Composite video input voltage (peak -to- peak value); pin 16 Storage temperature range Operation ambient temperature range w w w t a .D S a e h 7.2 -25 -25 U 4 t e MIN. .c 1 m o 8 ORDERING INFORMATION ILA8395N DIP TA = -40° to 125°C MAX.

During frame retrace a 4.433619 MHz reference frequency is used to calibrate the filters and the demodulator. The reference frequency should be very stable during this period.
