The ICS7151 is a clock generator produced by ICST company. It can be used for EMI (Electro Magnetic Interference) reduction. The product has 3.3V ±0.3 V voltage, 8-pin SOIC package, Pb (lead) free package. The input frequency range is 16.5 to 33.4 MHz, and the output frequency range is 8.3 to 16.7 MHz, 16.5 to 33.4 MHz, 33.3 to 66.7 MHz, 66.6 to 133.4 MHz. The product supports ±0.5%, ±1.5% center spread, -1.0%, -3.0% down spread, and x1/2, x1, x2, x4 multiplication rates.
The ICS7151 is a spread‑spectrum clock generator designed to reduce EMI by modulating the oscillator frequency. It supports multiple multiplication ratios (x1/2, x1, x2, x4) and offers selectable center‑spread and down‑spread profiles.
