Texas Instruments LMK6CE10000CDLFR

Overview

LMK6CE10000CDLFR 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 –72 dBc PSRR at 500 kHz and supports fast <5 ms start-up-used as a reference clock for FPGA/ASIC timing in industrial edge controllers and high-reliability data acquisition systems.

For engineers reviewing the LMK6CE10000CDLFR datasheet, LMK6CE10000CDLFR pinout, LMK6CE10000CDLFR application, or LMK6CE10000CDLFR equivalent, key selection criteria include its extended-temperature LVCMOS output, BAW-based jitter performance at 100 MHz, integrated power conditioning, and compatibility with tight-layout SERDES reference clocking where crystal oscillators lack stability or size efficiency.

Technical Context

The LMK6CE10000CDLFR implements a monolithic BAW resonator co-packaged with fractional-N frequency synthesis and LVCMOS output driver circuitry, eliminating external crystal load capacitance and trimming components. Its architecture includes a temperature-compensated control loop and integrated LDO that isolates the resonator core from supply noise.

It operates exclusively in fixed-frequency mode-factory-programmed to 100.000 MHz-and supports active output enable (OE) or standby (ST) control via Pin 1. The device uses a 4-pin VSON (DLF-4) package with 2.5 mm × 2.0 mm footprint and thermal resistance R_θJA = 128.1 °C/W.

FAQ

Is LMK6CE10000CDLFR programmable in-system?

No. LMK6CE10000CDLFR is factory-programmed to 100.000 MHz and cannot be reconfigured post-manufacture. It lacks I²C/SPI interface or user-accessible registers. Frequency, output type, and voltage are fixed at production-confirmed by TI's OPN decoder and SNAS826G datasheet Section 4.

What is the maximum capacitive load for the LVCMOS output?

The LVCMOS output supports up to 15 pF for frequencies above 50 MHz and up to 30 pF for frequencies below 50 MHz, per Section 6.7 of the SNAS826G datasheet. At 100 MHz, CL ≤ 15 pF ensures rise/fall time remains within 0.5–1 ns and duty cycle stays within 45–55%.

Does LMK6CE10000CDLFR require external decoupling capacitors?

Yes. TI specifies two 100 nF X7R ceramic capacitors-one between VDD and GND near Pin 4, and one between OE/ST and GND near Pin 1-to stabilize the internal LDO and suppress high-frequency noise. Omitting them degrades PSRR and increases RMS jitter beyond 500 fs.

Can LMK6CE10000CDLFR operate at 1.8 V supply?

No. LMK6CE10000CDLFR is rated for 2.5 V or 3.3 V ±5% only. The "C" suffix in the part number denotes the 2.5 V/3.3 V voltage grade and extended temperature range (–40°C to +105°C); 1.8 V operation is supported only by "D"-suffix variants like LMK6DE10000CDLFR.
