TRC-70
CIRCUIT DESCRIPTION
PLL (Phase Locked Loop)
The TRC-70 PLL is divided into a HET loop and a
CAR loop. The HET loop consists of loop A and loop B,
determined by the 30.3 MHz oscillation circuit.
and the CAR loop consists of loop C. Figures 2 and 3
show a block diagram of the HET and CAR loops. The
following paragraphs describe loops A, B, and C.
