Satellite sound receiver with I²C-bus control
Preliminary specification
TDA8745
DC CHARACTERISTICS
All voltages referenced to ground (pins 6, 10, 14 and 32). In accordance with the block diagram (see Fig.1);
V_P1 = V_P2 = 5 V; V_P3 = 12 V; T_amb = 25 °C; f_OS1 = 10.7 MHz; f_OS2 = 10.52 MHz (no modulation; see note 1); unless
otherwise specified.

Notes
1. Presence of both carriers is required to achieve lock of the PLLs; otherwise not all pins will have a stable DC voltage.
2. Pin 7 and 8 functioning as normal inputs (bit PE = 0).
