DSC8102 DSC8122 Programmable Low-Jitter Precision LVPECL Oscillator General Description The DSC8102 & DSC8122 series of high performance field-programmable oscillators utilizes a proven silicon MEMS technology to provide excellent jitter and stability over a wide range of supply voltages and temperatures. Using the TIMEFLASH programmer, the end user can easily program the oscillators’ frequency in the field for immediate testing or use in advance prototype development or production. DSC8102 has a standby feature allowing it to completely power-down when EN pin is pulled low; whereas for DSC8122, only the outputs are disabled when EN is low. Both oscillators are available in industry standard packages, including the small 3.2x2.5 mm2, and are “drop-in” replacement for standard 6-pin LVPECL quartz oscillators.
