Pin Applications
1. Crystal Clock Oscillator: Pins XIN1, XOUT1, XIN2, XOUT2, N/P1, N/P2, FSC, CSYNC, 2FSC and VSYNC
The XIN1 and XOUT1 pins are for use with a 14.31818 MHz (NTSC) crystal oscillator. The XIN2 and XOUT2 pins
are for use with a 17.734476 MHz (PAL) crystal oscillator. The LC7871E and LC7871NE provide the above two
crystal oscillator systems. Depending on the application, either a single crystal can be connected, or alternatively two
crystals can be used allowing control from both the N/P1 and the N/P2 pins. The N/P1 pin switches the RGB encoder
block between PAL and NTSC and the N/P2 pin switches the CD-G decoder block between PAL and NTSC. The
FSC and 2FSC pins output the crystal oscillator frequency divided by 4 and 2 (2/5 in PAL mode) respectively. The
CSYNC pin outputs a composite sync signal, and the VSYNC pin outputs a vertical sync signal.
The table below shows the pin outputs in the various modes.
