Texas Instruments LMK6CE10000DDLFR

Overview

LMK6CE10000DDLFR 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, integrated LDO for –72 dBc PSRR at 500 kHz, and <5 ms start-up time. It serves as a high-stability reference clock for FPGA/ASIC timing, industrial control systems, and PCIe Gen 1–7 compliant applications requiring robust supply noise immunity.

For engineers reviewing the LMK6CE10000DDLFR datasheet, LMK6CE10000DDLFR pinout, LMK6CE10000DDLFR application, or LMK6CE10000DDLFR equivalent, key selection criteria include its 100 MHz LVCMOS output, 0.25–0.5 ps RMS jitter (12 kHz–20 MHz), 1.8V/2.5V/3.3V supply flexibility, 4-pin VSON DLF-4 package (2.5 mm × 2.0 mm), and extended temperature operation up to +105°C.

Technical Context

The LMK6CE10000DDLFR implements TI's monolithic BAW resonator integrated directly into the VSON package, eliminating external crystal dependencies and enabling superior mechanical stability and shock resistance. Its fractional frequency divider architecture allows precise factory programming of fixed-frequency outputs within 1–200 MHz range without external components.

Internal power conditioning includes an integrated LDO with –72 dBc PSRR at 500 kHz ripple, ensuring low sensitivity to supply noise. The device supports active-high output enable (OE) and operates across full industrial temperature range with guaranteed 10-year aging stability included in ±25 ppm total tolerance.

FAQ

What is the recommended power supply decoupling for LMK6CE10000DDLFR?

A 100 nF X7R ceramic capacitor placed within 2 mm of the VDD pin and a 1 µF tantalum or ceramic capacitor on the same power net are required. The integrated LDO reduces sensitivity to ripple, but proper local decoupling remains essential to maintain <0.5 ps RMS jitter performance and prevent coupling into adjacent high-speed traces.

Can LMK6CE10000DDLFR be used as a drop-in replacement for a 100 MHz quartz oscillator?

Yes-its 4-pin VSON DLF-4 footprint matches standard 2.5 mm × 2.0 mm quartz oscillator layouts, and LVCMOS output levels comply with JEDEC JESD8-12 standards. No external load capacitors or pull-ups are needed, simplifying layout and eliminating crystal matching uncertainties.

Does LMK6CE10000DDLFR support spread-spectrum clocking (SSC)?

No-this device is a fixed-frequency oscillator with no SSC modulation capability. It is factory-programmed for 100 MHz and lacks frequency control pins or I²C interface. For SSC requirements, TI recommends the LMK05318 or LMK5B33414 clock generators.

What is the maximum capacitive load the LMK6CE10000DDLFR LVCMOS output can drive?

The output is specified for ≤15 pF when operating above 50 MHz. At 100 MHz, exceeding this load increases rise/fall time beyond 1 ns and degrades jitter; for heavier loads, use a dedicated fanout buffer such as the SN74LVC1G125 or TI's CDCx235 series.
