DSC1103/23
Low-Jitter Precision LVDS Oscillator
Features
General Description
• Low RMS Phase Jitter: <1 ps (typ.)
The DSC1103 and DSC1123 series of high
performance oscillators utilizes a proven silicon MEMS
technology to provide excellent jitter and stability over
a wide range of supply voltages and temperatures. By
eliminating the need for quartz or SAW technology,
MEMS oscillators significantly enhance reliability and
accelerate product development, while meeting
stringent clock performance criteria for a variety of
communications, storage, and networking applications.
• High Stability: ±10 ppm, ±20 ppm, ±25 ppm,
±50 ppm
• Wide Temperature Range:
- Ext. Industrial –40°C to +105°C
- Industrial –40°C to +85°C
- Ext. Commercial –20°C to +70°C
• High Supply Noise Rejection: –50 dBc
• Wide Frequency Range:
DSC1103 has a standby feature allowing it to
completely power-down when EN pin is pulled low. For
DSC1123, only the outputs are disabled when EN is
low. Both oscillators are available in industry standard
packages, including the smallest 2.5 mm x 2.0 mm,
and are drop-in replacements for standard 6-pin LVDS
crystal oscillators.
