ICS ICS5OSK481
The ICS5OSK481 is a low cost integrated clock synthesizer solution designed for replacing crystals and crystal oscillators. The ICS5OSK481 generates a very accurate 48.00 MHz clock output. External Components Decoupling Capacitor As with any high-performance mixed-signal IC, the ICS5OSK481 must be isolated from system power supply noise to perform optimally.DESCRIPTION
