P1820, P1818 Datasheet - Alliance Semiconductor

P1820 (P1818 - P1822) Low Power Mobile VGA EMI Reduction IC

The P18xx is a versatile spread spectrum frequency modulator designed specifically for a wide range of input clock frequencies from 10 to 160 MHz (see Input Frequency and Modulation Rate Selections). The P18xx can generate an EMI reduced clock from crystal, ceramic resonator, or system clock. The P1.
