Product details

MEMS resonator replaces quartz in LVDS clock generation

The DSC1103AE1-083.3333 is a MEMS-based XO (Standard) that outputs LVDS at 83.3333 MHz — a frequency commonly used as a reference clock for 10 Gigabit Ethernet PHYs, PCIe Gen 1/2/3, and SFP+ modules.

Wide supply range simplifies rail assignment

Maximum active current is 32 mA; standby (power-down) current drops to 95 µA, making it suitable for power-gated designs.

Active lifecycle – no obsolescence pressure

Microchip lists the DSC1103AE1-083.3333 as Active.

6-SMD package with exposed pad – thermal and layout notes

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm (0.276" x 0.197") with a seated height of 0.90 mm (0.035").

Frequently asked questions

Is DSC1103AE1-083.3333 a drop-in replacement for a standard LVDS crystal oscillator?

Yes, it is a drop-in replacement for any 6-pin LVDS oscillator in the same 7.00 mm x 5.00 mm footprint with the same pinout (standby pin, no connect, supply, ground, output, complement). The MEMS resonator makes it more shock- and vibration-tolerant than quartz-based equivalents, but the electrical interface is identical.

Can DSC1103AE1-083.3333 operate with a 2.5 V supply?

Yes. The supply voltage range is 2.25 V to 3.63 V, so 2.5 V is well within the operating window. The LVDS output common-mode voltage and swing will shift proportionally with the supply, but remain within the LVDS receiver input range as long as the receiver is referenced to the same supply.

What is the frequency stability of DSC1103AE1-083.3333?

The frequency stability is ±50 ppm over the -20°C to 70°C operating temperature range. This includes initial tolerance, temperature drift, and aging effects. For applications requiring tighter stability (e.g., ±25 ppm for SyncE), consider the DSC1103 series variants with higher stability grades.

Does DSC1103AE1-083.3333 have spread spectrum capability?

No. The DSC1103 series does not include spread spectrum modulation. The output is a fixed-frequency LVDS clock. For spread spectrum clocking, look at Microchip's DSC400 or DSC6000 families.
