LC72121

PLL Frequency Synthesizers for Electronic Tuning

ON Semiconductor 

LC72121, 72121M, 72121V

Serial Data Input (IN1/IN2) tSU, tHD, tEL, tES, tEH ≥ 0.75 µs tLC < 0.75 µs

• CL: Normally high

• CL: Normally low

Serial Data Output (Out) tSU, tHD, tEL, tES, tEH ≥ 0.75 µs tDC, tDH < 0.35 µs

• CL: Normally high

• CL: Normally low

Note: The data conversion times (tDC and tDH) depend on the value of the pull-up resistor and the printed circuit board capacitance since the DO pin is an

n-channel open-drain circuit.

No. 5815-12/23
