Crystal-less™ Configurable Clock Generator
General Description
The DSC2044FL1-F0022 is a programmable, high
performance dual HCSL output oscillator utilizing
Micrel's proven silicon MEMS technology to provide
excellent jitter and stability while incorporating
additional device functionality. Two HCSL outputs
are controlled by separate supply voltages to allow for
high output isolation. The frequencies of the outrputs
can be identical or independently derived from a
common PLL frequency source.
The DSC2044FL1-F0022 has provision for up to eight
user-defined pre-programmed, pin-selectable output
frequency combinations.
Features
• Frequency and output formats:
- HCSL
100MHz
- HCSL
100MHz
• Low RMS phase jitter: <1ps (typ)
• ±50ppm frequency stability
• -40°C to +105°C ext. industrial temperature range
• High supply noise rejection: -50dBc
• Pin-selectable configurations
- Up to 8 output frequency combinations
• Excellent shock & vibration immunity
- Qualified to MIL-STD-883
• High reliability
- 20x better MTF than quartz oscillators
• Supply range of 2.25 to 3.6V
• AEC-Q100 automotive qualified
• 14-pin 3.2mm x 2.5mm QFN package
