Product Overview
The DSC8103 & DSC8123 series are high-performance, field-programmable LVDS oscillators utilizing silicon MEMS technology. They offer excellent jitter and stability across a wide range of supply voltages and temperatures. The TIMEFLASH programmer allows users to program the frequency in the field, making them suitable for immediate testing, prototype development, or production. The DSC8103 features a standby mode that powers down the device when the EN pin is low, while the DSC8123 only disables its outputs. Both are available in industry-standard packages, serving as drop-in replacements for standard 6-pin LVDS quartz oscillators.
