Frequently Asked Questions
Why is LVDS output preferred for the 50 MHz clock in DSC1123AM2-050.0000?
LVDS (Low-Voltage Differential Signaling) output reduces electromagnetic interference and supports higher clock frequencies by transmitting complementary signals on two traces terminated with 100 ohms. At 50 MHz, the differential swing of approximately 350 mV provides noise immunity in mixed-signal PCBs, preventing clock jitter caused by nearby switching power supplies or high-current digital logic.
How does the enable/disable pin on DSC1123AM2-050.0000 help in a power-managed system?
The enable/disable control input allows the host microcontroller or FPGA to gate the 50 MHz clock output during low-power states, cutting the oscillator's active current draw from its typical operating level to near-zero. In battery-powered industrial sensors that sleep most of the time, gating the clock can reduce average system power by several milliwatts, extending battery life by hours or days.
What advantage does MEMS technology give DSC1123AM2-050.0000 over quartz oscillators in harsh environments?
MEMS resonators are manufactured using semiconductor lithography, producing a monolithic silicon structure with no moving macroscopic parts, giving them 10x to 100x better shock resistance than quartz crystal blanks. This makes DSC1123AM2-050.0000 suitable for industrial robots, vehicle telematics units, and outdoor communications gear exposed to vibration levels exceeding 50 G.
Which PCB termination scheme is required for DSC1123AM2-050.0000's differential output?
DSC1123AM2-050.0000 specifies a 100-ohm differential termination resistor placed as close as possible to the receiving LVDS input pins on the FPGA or clock buffer. Using a 49.9-ohm resistor to ground on each output line (AC-coupled) or a single 100-ohm resistor across the differential pair ensures correct signal integrity and prevents reflections at 50 MHz that would degrade clock edge quality.
