Manufacturer: SANYO (now Panasonic)

Overview

Ordering number : EN*5815A CMOS IC LC72121, 72121M, 72121V PLL Frequency Synthesizers for Electronic Tuning Preliminary Overview The LC72121 and the LC72121M and the LC72121V are high input.

Key Features

  • e frequency, and a low level is output when that frequency is lower. This pin goes to the highimpedance state when the frequencies match. AIN AOUT 19 20 20 21 Low-pass filter.
  • Connections for the MOS transistor used for the PLL active low-pass amplifier filter. transistor IFIN 12 13 IF counter.
  • The input frequency range is 0.4 to 12 MHz.
  • The signal is passed directly to the IF counter.
  • The result is output, MSB first, through the DO.
