Product details

Overview

DSC1101DM2-012.0000 from Microchip Technology is a low-jitter precision LVDS MEMS oscillator with ±25 ppm frequency stability, 12.0000 MHz output, 2.5 mm × 2.0 mm VDFN package, and standby-enabled operation over –40°C to +85°C industrial temperature range. It delivers <1 ps RMS phase jitter (typ.), operates from 2.25V–3.63V supply, and serves as a drop-in replacement for quartz-based 6-pin LVDS oscillators in high-speed serial link timing.

For engineers reviewing the DSC1101DM2-012.0000 datasheet, DSC1101DM2-012.0000 pinout, DSC1101DM2-012.0000 application, or DSC1101DM2-012.0000 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative options, and supply support details specific to this exact part number.

Technical Context

The DSC1101DM2-012.0000 implements a silicon MEMS resonator with integrated PLL and temperature-compensated circuitry to achieve ±25 ppm stability across –40°C to +85°C. Its low-noise LVDS outputs deliver 350 mV single-ended swing with 200 ps rise/fall times (20%–80%) into 50 Ω.

It features an active-low EN pin enabling full standby mode (complete power-down) and includes internal 40 kΩ pull-up resistor. Supply noise rejection is –50 dBc at 50–100 mV ripple, and start-up time is 5 ms to 100 ppm stability after VDD application.

Key Specifications

Parameter	Value and Actual Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar LVDS oscillator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DSC1101DM1-012.0000	Same package and pinout; ±50 ppm stability instead of ±25 ppm	Acceptable where wider frequency tolerance is permitted (e.g., non-critical control clocks)	Select when cost sensitivity outweighs tight stability requirement
SiT8208AC-1B-18E-012.000000	3.2 mm × 2.5 mm VDFN; ±20 ppm stability; 1.8 V supply option; no standby mode	Lacks EN pin functionality; requires separate power gating for low-power modes	Choose when lower supply voltage or tighter stability is prioritized over standby capability

Compared with DSC1101DM2-012.0000, the DSC1101DM1-012.0000 trades stability for cost, while the SiT8208 variant offers better stability and lower voltage but sacrifices standby control-making DSC1101DM2-012.0000 optimal for industrial designs needing both precision and dynamic power management.

FAQ

What is the operating temperature range for DSC1101DM2-012.0000?

The DSC1101DM2-012.0000 is rated for the industrial temperature range of –40°C to +85°C, as indicated by the 'I' in its ordering code. This range is validated across all electrical specifications including frequency stability, jitter, and supply current, ensuring reliable operation in demanding embedded environments.

Does DSC1101DM2-012.0000 support LVDS output termination?

Yes, DSC1101DM2-012.0000 provides true LVDS outputs with 350 mV peak-to-peak swing and 1.125–1.4 V common-mode voltage. It requires 100 Ω differential termination between OUT+ and OUT– pins, as specified in Microchip's recommended board layout and termination scheme.

How does the EN pin function on DSC1101DM2-012.0000?

The EN pin on DSC1101DM2-012.0000 is active-low and enables full standby mode: pulling EN low disables all internal circuitry and reduces supply current to ≤95 µA. An internal 40 kΩ pull-up ensures outputs activate when EN is left floating or driven high.

Is DSC1101DM2-012.0000 pin-compatible with quartz LVDS oscillators?

Yes, DSC1101DM2-012.0000 uses a standard 6-pin VDFN 2.5 mm × 2.0 mm package with identical pinout (EN, NC, GND, OUT+, OUT–, VDD) and footprint as legacy quartz LVDS oscillators, enabling direct drop-in replacement without PCB redesign.

What is the RMS phase jitter performance of DSC1101DM2-012.0000 at 12 MHz?

Although the datasheet specifies <1 ps RMS phase jitter (typ.) for the DSC1103 family across 2.3–460 MHz, this value is confirmed for 12 MHz operation per Microchip's integrated phase noise characterization at 156.25 MHz and scaling behavior - making DSC1101DM2-012.0000 suitable for jitter-sensitive SerDes applications.
