DSC8101 DSC8121 Programmable Low-Jitter Precision CMOS Oscillator General Description Features The DSC8101 & DSC8121 series of high Low RMS Phase Jitter: <1 ps (typ) performance field-programmable oscillators High Stability: 10, 25, 50 ppm utilizes a proven silicon MEMS technology to provide excellent jitter and stability over a Wide Temperature Range wide range of supply voltages and o Automotive: -55 to 125 C temperatures. Using the TIMEFLASH o Ext. Industrial: -40 to 105 C programmer, the end user can easily o Industrial: -40 to 85 C program the oscillators frequency in the field o Ext. commercial: -20 to 70 C for immediate testing or use in advance prototype development or production. High Supply Noise Rejection: -50 dBc Short Lead Time: 2 Weeks DSC8101 has a standby feature allowing it to completely power-down when EN pin is Wide Freq. Range: 10 to 170 MHz pulled low whereas for DSC8121, only the Small Industry Standard Footprints outputs are disabled when EN is low. Both o 2.5x2.0, 3.2x2.5, 5.0x3.2, & 7.0x5.0 mm oscillators are available in industry standard 2 packages, including the small 3.2x2.5 mm , Excellent Shock & Vibration Immunity and are drop-in replacement for standard o Qualified to MIL-STD-883 4-pin CMOS quartz oscillators. High Reliability o 20x better MTF than quartz oscillators Low Current Consumption Supply Range of 2.25 to 3.6 V Block Diagram Standby & Output Enable Function Lead Free & RoHS Compliant Applications 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 Output Enable Modes HD/SD/SDI Video & Surveillance EN Pin DSC8101 DSC8121 PCI Express High Output Active Output Active DisplayPort NC Output Active Output Active Low Standby Output Disabled DSC8101 DSC8121 Page 1 MK-Q-B-P-D-030411-01-2 Programmable Low-Jitter Precision CMOS Oscillator DSC8101 DSC8112 1 Absolute Maximum Ratings Ordering Code Item Min Max Unit Condition Temp Range E: -20 to 70 Supply Voltage -0.3 +4.0 V Enable Modes Packing I: -40 to 85 0: Enable/Standby T: Tape & Reel L: -40 to 105 Input Voltage -0.3 V +0.3 V DD 2: Enable/Disable : Tube M: -55 to 125 Junction Temp - +150 C Storage Temp -55 +150 C DSC81 0 1 C I 5 125.0000 T - Soldering Temp - +260 C 40sec max.
