DSC8104 DSC8124
Programmable Low-Jitter Precision HCSL Oscillator
General Description
The DSC8104 & DSC8124 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.
DSC8104 has a standby feature allowing it to completely power-down when EN pin is pulled low; whereas for DSC8124, 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 HCSL quartz oscillators.
