Product details
Overview
MK3200SILF from IDT is a low-power, industrial-grade 32.768 kHz clock oscillator with integrated crystal drive circuitry, power-down control (PD), and output enable (OE) for tri-state operation. It operates from 2.5 V to 5 V, draws only 3.5 µA in normal mode, and supports in-circuit testing in battery-powered real-time clock (RTC) subsystems.
For engineers reviewing the MK3200SILF datasheet, MK3200SILF pinout, MK3200SILF application, or MK3200SILF equivalent, key selection criteria include its -40°C to +85°C temperature range, SOIC-8 packaging, OE/PD dual-control interface, and compatibility with standard 32.768 kHz parallel-mode crystals with 12 pF load capacitance.
Technical Context
The MK3200SILF integrates a CMOS oscillator core with crystal input terminals (X1/X2), a buffered 32.768 kHz CMOS output (32.768k), and two digital control inputs: PD (power-down) and OE (output enable). Its architecture enables full chip disable (PD = high) and output high-impedance state (OE = low) independently.
It uses an advanced sub-micron CMOS process optimized for ultra-low quiescent current and stable oscillation across industrial temperatures. The device requires no external feedback resistors and accepts only a parallel-resonant 32.768 kHz crystal - not a pre-oscillated clock signal - as its timing reference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 32.768 kHz ±30 ppm - meets RTC timing accuracy requirements for calendar/timekeeping functions |
| Supply Voltage Range | 2.375 V to 5.25 V - supports direct connection to 3.3 V or 5 V rails without level-shifting |
| Quiescent Current | 3.5 µA at VDD = 3.3 V - enables multi-year battery life in coin-cell–powered RTC modules |
| Operating Temperature | -40°C to +85°C - qualified for industrial environments including automotive cabin and smart metering |
| Output Logic Level | CMOS-compatible VOH ≥ VDD−0.4 V, VOL ≤ 0.4 V - ensures reliable interfacing with standard microcontroller RTC inputs |
| Rise/Fall Time | 8 ns typical (20%–80%) - minimizes jitter contribution in timing-sensitive sampling paths |
| Duty Cycle | 40%–60% at VDD/2 - maintains symmetrical clock edges for low-phase-noise timebase generation |
Pinout & Package
Packaged in 8-pin SOIC (150 mil body), JEDEC MS-012 compliant, with lead-free finish. Pin 1 marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| X1 | Crytal Input | Connects to one terminal of external 32.768 kHz parallel-mode crystal (12 pF load) |
| VDD | Power Supply | Primary supply rail (2.375–5.25 V); requires 0.01 µF decoupling capacitor placed adjacent to pin |
| GND | Ground Reference | System ground return; two dedicated GND pins (pins 3 and 7) reduce ground bounce |
| 32.768k | CMOS Clock Output | Buffered 32.768 kHz square wave output; 20 Ω nominal impedance; series-terminate with 33 Ω if trace >1 inch |
| OE | Digital Control Input | Output Enable: high = active output, low = tri-state (Hi-Z) for in-circuit test isolation |
| PD | Digital Control Input | Power Down: high = entire oscillator disabled (IDD ≈ 0 µA), low = normal operation |
| GND | Ground Reference | Second ground connection; improves noise immunity and thermal dissipation |
| X2 | Crytal Output | Connects to second terminal of external 32.768 kHz crystal; completes resonator loop |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32.768 kHz oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ABRACON ABM3B-32.768KHZ-T | Fixed-output crystal oscillator (XO), no PD/OE pins; consumes 0.9 µA but lacks digital control | Best for simple, always-on RTC where control flexibility is unnecessary | Select when lowest power is critical and system-level control of clock enable/disable is handled externally |
| EPSON SG-210SCB 32.768000kHz | SPXO with 1.8 V–3.3 V supply; 1.2 µA typical current; no PD/OE; ±20 ppm initial tolerance | Suitable for space-constrained designs needing tighter initial accuracy but no in-system test features | Choose when higher initial accuracy and lower voltage operation outweigh need for tri-state or power-down capability |
Compared with ABRACON ABM3B-32.768KHZ-T and EPSON SG-210SCB, the MK3200SILF uniquely provides both power-down and output-enable control in a single SOIC-8 package - enabling dynamic power management and in-circuit testability not available in basic XO alternatives.

FAQ
What is the operating temperature range of the MK3200SILF?
The MK3200SILF is rated for industrial operation from -40°C to +85°C. This range is confirmed in the "Recommended Operation Conditions" table on page 4 of the official datasheet (Rev H, 073012), and applies to all electrical specifications including frequency stability, supply current, and output drive strength. The MK3200SILF achieves this via process and design optimizations in its sub-micron CMOS oscillator core.
Does the MK3200SILF require an external crystal?
Yes, the MK3200SILF requires an external 32.768 kHz parallel-resonant crystal connected between X1 and X2 pins. The datasheet specifies a 12 pF load capacitance and prohibits use of pre-oscillated clock signals. Unlike fixed-output XOs, the MK3200SILF is a crystal oscillator IC - it integrates the sustaining amplifier but relies on an external resonator for frequency determination.
How do the PD and OE pins function independently on the MK3200SILF?
On the MK3200SILF, PD (pin 6) controls overall power: when high, the entire oscillator circuit is disabled and supply current drops near zero. OE (pin 5) controls only the output buffer: when low, the 32.768k output enters high-impedance state without affecting internal oscillation. Both functions are documented in the "Power Down Select Table" and "Output Enable Select Table" on page 2 of the datasheet.
What is the recommended decoupling capacitor for the MK3200SILF?
A 0.01 µF ceramic capacitor must be placed between VDD (pin 2) and GND (pin 3), mounted on the component side of the PCB as close to the VDD pin as possible, with no vias in the path. This requirement is explicitly stated in the "External Components" section (page 3) and is critical to suppress supply noise that could degrade phase noise and frequency stability.
Is the MK3200SILF pin-compatible with other members of the MK32xx family?
Yes, the MK3200SILF shares identical pinout and package (8-pin SOIC) with other MK32xx variants such as MK3200SLF and MK3200GLF, as confirmed by the unified "Pin Assignment" diagram on page 2 and consistent pin descriptions across the datasheet. Functional differences (e.g., temperature grade, package type) do not affect mechanical or electrical pin compatibility.
