Product details
Overview
LMK6CE10000DDLFT from Texas Instruments is a factory-programmed, ultra-low-jitter LVCMOS bulk-acoustic wave (BAW) oscillator delivering 100 MHz output with ±25 ppm total frequency stability over –40°C to +105°C, 3.3 V supply, and 350 fs typical / 500 fs maximum RMS jitter (12 kHz–20 MHz). It integrates an on-die LDO for –70 dBc PSRR at 500 kHz and supports fast <5 ms start-up - deployed as a high-reliability reference clock in FPGA/ASIC timing and industrial control systems.
For engineers reviewing the LMK6CE10000DDLFT datasheet, LMK6CE10000DDLFT pinout, LMK6CE10000DDLFT application, or LMK6CE10000DDLFT equivalent, this page delivers verified package mapping (DLF-4), confirmed 4-pin VSON layout, real-world PCIe Gen 7–compliant jitter performance, and direct substitution guidance against TI's LMK6C family alternatives.
Technical Context
The LMK6CE10000DDLFT implements a monolithic BAW resonator co-integrated with fractional-N frequency synthesis and LVCMOS output driver circuitry - eliminating external crystal and load capacitors. Its internal LDO rejects supply ripple up to –70 dBc at 500 kHz, while the temperature-compensated control loop maintains ±25 ppm stability across 10 years of aging and full industrial temperature range.
Pin configuration includes dedicated OE/ST function pin (active-high enable or active-low standby), single-ended LVCMOS output, and rail-to-rail compatible 1.8 V / 2.5 V / 3.3 V operation. The device is pre-programmed at factory for fixed 100.000 MHz output, eliminating configuration overhead in production.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 100.000 MHz - factory-trimmed, no user programming required. |
| RMS Jitter (12 kHz–20 MHz) | 350 fs typical / 500 fs max - meets stringent SERDES reference clock requirements for 100G+ optical interfaces. |
| Frequency Stability | ±25 ppm total - includes initial tolerance, temp drift (–40°C to +105°C), voltage variation, and 10-year aging. |
| Supply Voltage | 3.3 V ±5% - supports industrial-grade power rails without external regulation. |
| Start-up Time | <5 ms - enables rapid system boot in real-time control and test equipment. |
| PSRR @ 500 kHz | –70 dBc - integrated LDO suppresses switching noise from DC/DC converters, reducing need for ultra-low-noise LDOs. |
| Package | DLF-4 (2.5 mm × 2.0 mm VSON) - smallest standard industry footprint for space-constrained PCB layouts. |
Pinout & Package
LMK6CE10000DDLFT uses a 4-pin VSON package (DLF-4, 2.5 mm × 2.0 mm), optimized for low-inductance ground return and minimal board area. Pin 1 is OE/ST (output enable or standby control), Pin 2 is GND, Pin 3 is OUT (LVCMOS clock output), and Pin 4 is VDD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | OE / ST / NC | Configurable as active-high output enable or active-low standby; floating = default enabled operation. |
| Pin 2 | GND | Dedicated ground terminal - must be connected directly to low-impedance PCB ground plane. |
| Pin 3 | OUT | LVCMOS single-ended clock output - 0.66 V VOL / 2.64 V VOH at 3.3 V, 2.2 pF load, 50% duty cycle. |
| Pin 4 | VDD | Primary power input - accepts 3.3 V ±5%; internal LDO regulates core logic and BAW resonator bias. |
Key Features
| Feature | Design Value |
|---|---|
| Bulk-Acoustic Wave (BAW) Resonator | Monolithic silicon-based resonator replaces quartz crystal - eliminates aging drift, shock sensitivity, and external load caps. |
| Integrated LDO Regulator | –70 dBc PSRR at 500 kHz ripple - enables direct connection to noisy switcher outputs without additional filtering. |
| Extended Temperature Range | –40°C to +105°C operation - qualified for industrial motor drives, base station radios, and automotive under-hood modules. |
| Ultra-Small DLF-4 Package | 2.5 mm × 2.0 mm footprint - reduces board area by >40% vs. legacy 3.2 mm × 2.5 mm oscillators. |
| Fast Start-up & Enable Control | <5 ms power-on stabilization; sub-25 µs output enable/disable - supports dynamic power gating in battery-powered test gear. |
Applications
| 5G Baseband Unit Timing | FPGA Reference Clocking |

IC Role / Device Role / Timing Role: Fixed-frequency LVCMOS clock source replacing crystal + buffer solutions. Use Value: Eliminates external matching network and reduces BOM count by two components per channel. |
| Industrial PLC Real-Time Control | Optical Transport Network Line Cards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-frequency LVCMOS oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMK6CE10000DDFFT | Same 100 MHz output, identical specs, but in larger DLE-4 (3.2 mm × 2.5 mm) package. | Preferred where thermal margin >124 °C/W RθJA is needed or board layout allows larger footprint. | Select when mechanical clearance or thermal derating requires larger package; otherwise DLF-4 offers superior density. |
| Si510-100.000M-DLGR | 100 MHz LVCMOS oscillator with 1.5 ps RMS jitter (12 kHz–20 MHz), ±20 ppm stability, 2.5 V/3.3 V supply. | Higher jitter limits suitability for PCIe Gen 5+ or 100G+ coherent optics; better for general-purpose MCU clocks. | Choose only if lower cost outweighs 3× jitter penalty and reduced aging margin; not drop-in for TI BAW-critical paths. |
Compared with LMK6CE10000DDLFT, the DLE-4 variant trades size for slightly better thermal resistance, while the Si510 offers lower unit cost at the expense of 3× higher jitter and no BAW-based aging immunity - making the LMK6CE10000DDLFT optimal for long-life, jitter-sensitive deployments.

FAQ
Is LMK6CE10000DDLFT pin-compatible with other LMK6C variants?
Yes - all LMK6C devices use identical 4-pin DLF-4 or DLE-4 VSON packages and share the same pinout: Pin 1 (OE/ST), Pin 2 (GND), Pin 3 (OUT), Pin 4 (VDD). No PCB redesign is needed when migrating between 100 MHz variants or changing package size.
Does LMK6CE10000DDLFT require external load capacitance?
No - the LMK6CE10000DDLFT integrates full LVCMOS driver and termination. It drives standard 2.2 pF loads directly; no external capacitors, series resistors, or parallel termination are required for compliant signal integrity.
Can the output frequency be reprogrammed in-circuit?
No - LMK6CE10000DDLFT is factory-programmed for fixed 100.000 MHz operation. It lacks I²C/SPI interface or one-time programmable memory; frequency change requires ordering a new part number (e.g., LMK6CE12500DDLFT for 125 MHz).
What is the recommended decoupling for LMK6CE10000DDLFT?
A single 100 nF X7R ceramic capacitor placed within 2 mm of Pin 4 (VDD) and Pin 2 (GND) is sufficient. The integrated LDO relaxes decoupling demands - no ferrite beads or multi-capacitor stacks are needed for typical 3.3 V switcher supplies.
