Product details

The DSC1101CE1-011.2896T is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a fixed 11.2896 MHz CMOS output from a 2.25V to 3.6V supply rail.

The wide 2.25V to 3.6V supply range means the oscillator can run from a 2.5V or 3.3V rail without an external LDO. In standby, the 95 µA max draw lets the oscillator sit on a battery bus without draining the cell during long idle periods. The enable pin is active-low; pulling it high gates the output and drops the current.

Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, this oscillator fits tight PCB stacks. The 0.50 mm pitch VDFN footprint requires a soldermask-defined pad and a via-in-pad layout if the ground pad is used for thermal relief — confirm the land pattern with the datasheet before committing the board.

Frequently asked questions

Can DSC1101CE1-011.2896T be used as a drop-in replacement for a crystal oscillator?

Yes, if the existing crystal oscillator has a CMOS output and operates from a 2.25V to 3.6V supply. The MEMS-based DSC1101CE1-011.2896T is pin-compatible with many standard 6-VDFN oscillators. However, confirm the footprint and output drive strength against the original part's datasheet — the 35 mA max supply current is typical for a MEMS oscillator and may differ from a quartz oscillator's draw.

Is DSC1101CE1-011.2896T suitable for battery-powered devices?

Yes, for two reasons. First, the standby function drops supply current to 95 µA max, allowing the oscillator to be gated off during sleep. Second, the 2.25V minimum supply means it can run from a 2.5V rail or a nearly-depleted Li-ion cell without a boost converter. The 35 mA active draw is typical for a MEMS oscillator at 11.2896 MHz and should be budgeted into the system power budget.

What are the alternatives to DSC1101CE1-011.2896T?

Within the DSC1101 series, other frequency variants are available. Outside the series, any 11.2896 MHz CMOS-output oscillator in a 6-VDFN package with a 2.25V to 3.6V supply range is a functional equivalent — confirm the standby pin polarity and APR specification before substituting.

Does DSC1101CE1-011.2896T require external output terminations?

No. The CMOS output is designed to drive a standard logic load directly. For long traces or high capacitive loads, a series termination resistor (typically 22-33 ohms) placed near the output pin can reduce ringing — this is a general CMOS practice, not a requirement specific to this oscillator.
