Technical content
The ILA8395 is a self-calibrating, fully integrated SECAM decoder. The IC should preferably be used in conjunction with the PAL/NTSC decoder ILA8362 or ILA8366 and with the switched capacitor baseband delay circuit ILA4661. The IC incorporates HF and LF filters, a demodulator and an identification circuit (luminance is not processed in this IC). The IC nee ds 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. Device is functionally identical to the TDA8395 Philips.
