DSC8103 DSC8123 Programmable Low-Jitter Precision LVDS Oscillator Features General Description The DSC8103 & DSC8123 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. Low RMS Phase Jitter: <1 ps (typ) DSC8103 has a standby feature allowing it to completely power-down when EN pin is pulled low; whereas for DSC8123, 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 LVDS quartz oscillators. Small Industry Standard Footprints High Stability: 10, 25, 50 ppm Wide Temperature Range o Industrial: -40 to 85 C o Ext. commercial: -20 to 70 C High Supply Noise Rejection: -50 dBc Short Lead Time: 2 Weeks Wide Freq. Range: 10 to 460 MHz o 2.5x2.0, 3.2x2.5, 5.0x3.2, & 7.0x5.0 mm Excellent Shock & Vibration Immunity o Qualified to MIL-STD-883 High Reliability o 20x better MTF than quartz oscillators Low Current Consumption Supply Range of 2.25 to 3.6 V Standby & Output Enable Function Block Diagram Lead Free & RoHS Compliant LVPECL & HCSL Versions Available AEC-Q100 Automotive Qualified Applications Output Enable Modes EN Pin High NC Low DSC8103 Outputs Active Outputs Active Standby DSC8123 Outputs Active Outputs Active Outputs Disabled Storage Area Networks o SATA, SAS, Fibre Channel Passive Optical Networks o EPON, 10G-EPON, GPON, 10G-PON Ethernet o 1G, 10GBASE-T/KR/LR/SR, and FCoE HD/SD/SDI Video & Surveillance PCI Express: Gen 1 & Gen 2 DisplayPort All Rights Reserved.
