APPLICATION INFORMATION
The TDA 1302T is optimized for Philips CDM12
mechanisms and, subsequently, this application is
preferred.
Application with Philips CDM12
The CDM12 mechanism uses an N sub-laser diode
together with a P sub-monitor diode and, since TDA1302T

is optimized for this type, besides the standard
components CL and R
are required as illustrated in Fig.9.
As two central spot diodes are summed together inside the
pick-up unit, one input pin remains unused as shown in
Fig.10. Unused central spot inputs should be connected to
ground in order to eliminate noise contribution to the RF
and RFE signals.
