... Direct communication to photodiode optics; no external preprocessing. GENERAL DESCRIPTION The TDA1301T is a fully digital servo processor which has been designed to provide all servo functions, except the spindle motor control, in two-stage three-spot compact disc systems. The device offers a high degree of integration, combined with the low additional cost of external components ...

... C. When using proper tools, all other pins can be soldered in one operation within between 270 and 320 C. (Pulse-heated soldering is not recommended for SO packages.) For pulse-heated solder tool (resistance) soldering of VSO packages, solder is applied to the substrate by dipping extra thick tin/lead plating before package placement. 15 Product specification TDA1301T - HELD SOLDERING ) ...
