Explanation: The conversion ratio of the phase detector of 565 PLL (Monolithic PLL) Kφ = 1.4/π = 0.4458. 2. Given fo = 1.2kHz and V = 13v, find the lock-in range of monolithic Phase-Locked Loop.
A. ±575Hz
B. ±720Hz
C. ±150Hz
D. ±1kHz
Answer:A
Explanation: The conversion ratio of the phase detector of 565 PLL (Monolithic PLL) Kφ = 1.4/π = 0.4458. 2. Given fo = 1.2kHz and V = 13v, find the lock-in range of monolithic Phase-Locked Loop.
A. ±575Hz B. ±720Hz C. ±150Hz D. ±1kHz
Explanation: The lock-in range of monolithic PLL, △fL = ±(7.8×fo)/V = ±(7.8×1.2kHz)/13 = ±720Hz. 3. Find out the incorrect statement.
