148 MHz LVPECL MEMS oscillator with standby
The LVPECL output delivers the fast edge rates and low jitter that 10G Ethernet, Fibre Channel, and FPGA reference-clock sockets demand — but that output type also requires DC-terminated traces (typically 50 Ω to VCC-2 V) on the receiver side, so confirm the load termination before layout. Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an intermediate regulator. The wide input range also absorbs rail ripple up to a few hundred millivolts without pulling the output frequency off the ±50 ppm stability spec.
Standby power-down for idle links
That is a 600:1 reduction — useful on a port that wakes infrequently, such as a management interface on a remote radio head or a backup link that only activates on failover.
It fits indoor switchgear, server motherboards, and test equipment, but not outdoor base stations or engine-bay controllers where -40°C cold start is required. The 6-SMD no-lead package measures 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The 0.276" × 0.197" footprint is common across the DSC1102 family — a layout designed for one frequency in the series accepts any other with the same package code.
