The LC7218 by Sony Corporation is a CMOS LSI PLL frequency synthesizer optimized for AM/FM tuner circuits requiring high mounting densities. It is suitable for AV applications and features built-in reference frequency and unlock detection circuits, I/O ports, and a general-purpose counter.
Key electrical specifications include a maximum input frequency of 160 MHz at 100 mVrms on the FMIN pin, and ten selectable reference frequencies ranging from 1 kHz to 100 kHz. The device provides 7 output ports and 2 input ports. A general-purpose counter is available for frequency measurement up to 70 MHz on the HCTR pin, and period measurement on the LCTR pin. The PLL unlock detection circuit can detect phase differences as small as 0.55 µs.
Operating within a temperature range of -40°C to +85°C, the LC7218 supports a maximum supply voltage of 7.0V. It is available in DIP24S, MFP24, and MFP24S packages. The controller clock output is 400 kHz, and the clock time base output is 8 Hz. Serial data I/O supports CCB format communication.
160 MHz (with 100 mVrms input) using the built-in prescaler.
Seven output ports.
Ten selectable frequencies: 1, 5, 9, 10, 3.125, 6.25, 12.5, 25, 50, and 100 kHz.
-40°C to +85°C.
DIP24S, MFP24, and MFP24S.
Yes, it includes a 70 MHz general-purpose counter on the HCTR pin.
The circuit detects phase differences of 0.55, 1.11, 2.22, and 3.33 µs, with a maximum detection time of 3.33 µs.
