Application Notes
The recommended crystal oscillator for the LC7219 and
LC7219M is the Nihon Dempa Kogyo Co., Ltd. (NDK)
LN-X-0702 (NR-18 type) or the LN-P-0001 (AT-51
type). The oscillator is connected as shown in figure 13.
Table 8. Device parameters vs. crystal frequency
Figure 13. Crystal oscillator connection
The device parameters for crystal oscillator frequencies
3.6MHz and 7.2MHz are shown in table 8.
Typical Application
Figure 14 shows a TV/AM/FM system using the IF counting system for electronic tuning.

Figure 14. TV/AM/FM system
The FMIN, AMIN, HCTR, and LCTR inputs should be capacitively coupled using a capacitor in the range 50 to
100pF. These coupling capacitors should be as close as possible to their respective inputs to minimize the effects of
stray capacitance.
The IF signals measurement should be done afte the IF-IC SD (station detect) signal are activated.
The circuit characteristics for each mode, TV, FM and AM, are shown in table 9.
