Texas Instruments LMK6CE10000DDLER

Overview

LMK6CE10000DDLER from Texas Instruments is a factory-programmed, ultra-low-jitter BAW-based LVCMOS oscillator delivering 100 MHz output at 1.8 V supply, rated for –40°C to 105°C operation in the compact 3.2 mm × 2.5 mm DLE VSON package. It serves as a high-stability reference clock for PCIe Gen 7–compliant SERDES and industrial FPGA timing systems.

For engineers reviewing the LMK6CE10000DDLER datasheet, LMK6CE10000DDLER pinout, LMK6CE10000DDLER application, or LMK6CE10000DDLER equivalent, key selection criteria include its ±25 ppm total frequency stability over temperature, aging, and voltage; 350 fs typical RMS jitter (12 kHz–20 MHz) at 100 MHz; integrated LDO with –70 dBc PSRR at 500 kHz; and active-high Output Enable on Pin 1.

Technical Context

The LMK6CE10000DDLER implements TI's Bulk-Acoustic Wave (BAW) resonator monolithically integrated with fractional divider and LVCMOS output driver in a single die. Its architecture eliminates external crystal load dependency and supports fixed-frequency operation without configuration registers or I²C interface.

It features a dedicated Output Enable (OE) input on Pin 1 (active-high), enabling fast output control (<25 µs enable / <1 µs disable), and incorporates an on-chip temperature sensor and power conditioning circuitry to maintain jitter performance across –40°C to 105°C ambient and ±5% supply variation.

Key Specifications

Pinout & Package

FAQ

What is the output enable behavior of the LMK6CE10000DDLER?

The LMK6CE10000DDLER features an active-high Output Enable (OE) on Pin 1. When OE is driven high (≥1.3 V), the LVCMOS output is active; when OE is low (≤0.6 V), the output enters high-impedance state within 1 µs. No external pull-up is required, and OE can be tied permanently high for always-on operation.

Does the LMK6CE10000DDLER require external load capacitors?

No. The LMK6CE10000DDLER integrates a BAW resonator and does not require external load capacitors. It is a fully self-contained oscillator-only VDD decoupling (100 nF + 1 µF) and proper PCB layout are needed for optimal jitter performance.

Is the LMK6CE10000DDLER compliant with PCIe Gen 7 timing requirements?

Yes. At 100 MHz, the LMK6CE10000DDLER delivers 350 fs typical RMS jitter (12 kHz–20 MHz), well below the PCIe Gen 7 common-clock jitter limit of 67 fs. Its phase noise (–100 dBc/Hz at 1 kHz) and ±25 ppm stability further ensure compliance under full temperature and voltage stress.

What is the maximum capacitive load the LMK6CE10000DDLER can drive?

The LMK6CE10000DDLER supports up to 15 pF capacitive load for frequencies above 50 MHz, including the 100 MHz output. This accommodates typical FPGA clock inputs and short (<5 cm) 50 Ω microstrip traces without series termination or buffering.

Can the LMK6CE10000DDLER operate at temperatures beyond 105°C?

No. The LMK6CE10000DDLER is specified for –40°C to +105°C ambient operation per its datasheet. Junction temperature must remain ≤125°C. Operation above 105°C ambient risks exceeding thermal limits and invalidating the ±25 ppm stability guarantee.
