Product details

Supply voltage spans 2.25 V to 3.6 V — one BOM line covers both 2.5 V and 3.3 V rail designs. The 42 mA max supply current at 100 MHz is typical for a HCSL driver; the real power savings come in standby, where the disable pin drops draw to 95 µA max.

Standby mode — where the 95 µA matters

For a battery-backed real-time clock or a wake-on-LAN controller that keeps the oscillator powered but gated, that 95 µA is the idle floor — compare it against the 42 mA running draw to size the battery capacity.

Microchip lists the DSC1104CI5-100.0000T as Active. The 6-SMD, No Lead package (3.20 mm x 2.50 mm footprint, 0.90 mm seated height) reflows with standard lead-free profiles.

Frequently asked questions

Is the DSC1104CI5-100.0000T a standard HCSL oscillator?

Yes — it is a standard XO (Standard) type with HCSL output, 100 MHz frequency, and ±10 ppm stability. It is designed as a direct HCSL clock source and does not require external termination resistors beyond the standard 50 Ω to ground per HCSL specification.

What is the standby power consumption for the DSC1104CI5-100.0000T?

In standby (power-down) mode, the maximum supply current is 95 µA. The output is disabled and the internal oscillator is shut down, leaving only the control logic drawing current.

Can the DSC1104CI5-100.0000T replace a 100 MHz quartz oscillator with HCSL output?

Functionally yes — it provides the same 100 MHz HCSL output. The MEMS resonator offers better shock and vibration tolerance than quartz, and the ±10 ppm stability is comparable to a standard quartz XO. However, the pinout and footprint (6-SMD, No Lead, 3.2 x 2.5 mm) must match the existing PCB land pattern; confirm compatibility before substitution.
