Texas Instruments LMK6CE10000DDLET

Overview

LMK6CE10000DDLET from Texas Instruments is a factory-programmed, ultra-low-jitter BAW-based LVCMOS oscillator delivering 100 MHz output at 1.8 V supply, with ±25 ppm total frequency stability over –40°C to 105°C and 350 fs typical RMS jitter (12 kHz–20 MHz). It serves as a high-stability reference clock for FPGA and ASIC timing in industrial edge computing systems.

For engineers reviewing the LMK6CE10000DDLET datasheet, LMK6CE10000DDLET pinout, LMK6CE10000DDLET application, or LMK6CE10000DDLET equivalent, key selection criteria include its 4-pin DLE package, Output Enable (Pin 1) control logic, 100 MHz LVCMOS drive capability into ≤15 pF load, and guaranteed operation across extended industrial temperature range.

Technical Context

The LMK6CE10000DDLET integrates a Bulk-Acoustic Wave (BAW) resonator directly into its VSON package, eliminating external crystal dependency while achieving sub-0.5 ps RMS jitter performance. Its fractional output divider is factory-configured for fixed 100 MHz generation, with no user programming required.

It features an integrated LDO providing –72 dBc PSRR at 500 kHz ripple, enabling robust noise immunity in noisy power environments. The device supports active-high Output Enable on Pin 1 and achieves <5 ms start-up time from power-on, meeting fast-boot requirements in embedded controllers and networking line cards.

FAQ

What is the maximum capacitive load supported by the LMK6CE10000DDLET at 100 MHz?

The LMK6CE10000DDLET supports a maximum capacitive load of 15 pF when operating above 50 MHz, including PCB trace capacitance and receiver input capacitance. This is specified in the LVCMOS Output Characteristics table and verified across –40°C to +105°C. Exceeding 15 pF may degrade rise/fall time and increase jitter beyond the 500 fs maximum specification.

Does the LMK6CE10000DDLET require external configuration or programming after soldering?

No, the LMK6CE10000DDLET is factory-programmed for fixed 100 MHz LVCMOS output and requires no post-soldering configuration. All parameters-including frequency, voltage, output type, and function pin behavior-are permanently set during manufacturing. No I²C, SPI, or OTP programming is needed or supported.

How does the LMK6CE10000DDLET achieve ±25 ppm total frequency stability over 10 years?

The LMK6CE10000DDLET achieves ±25 ppm total stability by combining TI's BAW resonator's inherent aging resistance (<±1 ppm/year), precision factory trimming, and compensation for solder shift, temperature variation (–40°C to +105°C), and supply voltage drift (1.8 V ±5%). This is validated per JEDEC JESD22-A114 and included in the datasheet's LVCMOS Frequency Tolerance section.

Can the LMK6CE10000DDLET be used as a drop-in replacement for quartz-based oscillators in existing designs?

Yes, the LMK6CE10000DDLET is pin-compatible with standard 4-pin LVCMOS oscillators in the same DLE-4 (3.2 mm × 2.5 mm) footprint and operates with identical 1.8 V supply and load conditions. Its fast start-up (<5 ms), low jitter, and integrated LDO simplify migration-no schematic or layout changes are required beyond verifying decoupling capacitor placement per TI's layout guide.

What is the power supply rejection performance of the LMK6CE10000DDLET at 100 MHz output?

At 100 MHz output and 1.8 V supply, the LMK6CE10000DDLET exhibits –50 dBc to –55 dBc spur suppression for 50 mV sine-wave ripple at 50–1000 kHz, and 10 fs/mV jitter sensitivity to 100 kHz supply ripple. This performance is enabled by its integrated LDO and is measured per the LVCMOS PSRR Characteristics table in the official SNAS826G datasheet.
