ICS501B is a low cost clock multiplier launched by ICS company. It uses Phase-Locked Loop (PLL) technology to multiply the input clock of 5MHz to 15MHz. It has low output jitter, high compatibility and low power consumption.
The ICS501B is a low-cost oscillator designed to replace crystal oscillators in electronic systems. It utilizes Phase-Locked Loop (PLL) techniques to generate output clocks up to 20 MHz from a standard fundamental mode, inexpensive crystal. The device features stored multiplication factors allowing it to output nine different common frequencies from a single chip.
| Output clock frequencies | up to 20 MHz |
|---|---|
| Input crystal frequency | 5 MHz |
| Operating voltage | 3.3 V or 5.5 V |
| Output jitter | 25 ps (one sigma) |
| Drive capability | 25 mA |
| Supply Voltage | 3.14 V to 5.25 V |
| Ambient Operating Temperature | -40 to +85 °C |
| Package | 8 pin SOIC |
The device can produce output clocks up to 20 MHz.
No external power supply filtering is required for the ICS501B.
The chip supports nine selectable frequencies.
The clock output is tri-stated when the OE pin is taken low.
