Product details
Overview
LMK6DE050000ADLET from Texas Instruments is a factory-programmed, ultra-low-jitter BAW-based LVDS oscillator delivering a precise 50.000 MHz fixed output with ±25 ppm total frequency stability, 100 fs typical RMS jitter (12 kHz–20 MHz), and operation across 2.5V–3.3V supply at –40°C to +85°C - deployed as a reference clock in high-speed SERDES for optical transport and data center switches.
For engineers reviewing the LMK6DE050000ADLET datasheet, LMK6DE050000ADLET pinout, LMK6DE050000ADLET application, or LMK6DE050000ADLET equivalent, key selection criteria include its LVDS differential output compliance, DLE-6 3.2 mm × 2.5 mm VSON package, sub-125 fs jitter performance at 50 MHz, integrated LDO for PSRR >72 dBc at 500 kHz, and OE/ST function pin configuration.
Technical Context
The LMK6DE050000ADLET implements a Bulk-Acoustic Wave (BAW) resonator co-integrated with a high-performance fractional divider and LVDS output driver in a single die. Its architecture eliminates external crystal dependency while maintaining mechanical stability and low phase noise across temperature and voltage variation.
It operates exclusively in fixed-frequency mode, factory-programmed for 50.000 MHz with LVDS output, Pin 1 configured as Output Enable (Active High or NC), and supports fast start-up (<5 ms) and rapid output enable/disable (25 µs / 1 µs). No user programming or configuration interface is present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 50.000 MHz - factory-trimmed, stable reference for PCIe Gen 4+ and 100G+ SERDES lanes. |
| RMS Jitter (12 kHz–20 MHz) | 100 fs typical - meets PCIe Gen 5–7 common clock jitter limits (≤150 fs) at 50 MHz. |
| Frequency Stability | ±25 ppm total - includes aging over 10 years, temp (–40°C to +85°C), and voltage (±5% of 2.5V/3.3V). |
| Supply Voltage | 2.5V–3.3V ±5% - dual-voltage support enables drop-in replacement in legacy and new 2.5V/3.3V systems. |
| Output Type | LVDS - differential 350 mV typical swing, 1.2 V common-mode, compatible with TI, Intel, and Broadcom SERDES receivers. |
| Package | VSON (DLE-6), 3.2 mm × 2.5 mm - industry-standard footprint enabling high-density PCB layout in optical modules and line cards. |
| PSRR @ 500 kHz | –72 dBc - integrated LDO rejects power rail noise without requiring external filtering for clean clock synthesis. |
Pinout & Package
VSON (DLE-6) package: 3.2 mm × 2.5 mm, 6-pin exposed-pad variant with wettable flanks; RoHS-compliant, MSL1, rated for industrial temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE / ST / NC | Input: Output Enable (active-high) or Standby (active-low) or no-connect - configurable per factory programming; tied high for always-on operation. |
| 2 | No Connect | NC - internally unconnected; must be left floating or grounded per layout guidelines. |
| 3 | GND | Ground reference for analog/digital sections and thermal pad - requires solid plane connection for EMI and thermal performance. |
| 4 | OUTP | LVDS positive output - delivers complementary signal referenced to OUTN; requires 100 Ω differential termination. |
| 5 | OUTN | LVDS negative output - forms differential pair with OUTP; matched trace length critical for jitter integrity. |
| 6 | VDD | Power supply input - accepts 2.5V or 3.3V ±5%; requires local 100 nF + 1 µF decoupling adjacent to pin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-frequency oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMK6DE156250ADLET | Same LMK6D family, identical DLE-6 package and LVDS output, but factory-programmed for 156.250 MHz. | Targets 10G/25G Ethernet PHYs and PCIe Gen 3–4 where 156.25 MHz is required; not usable as direct 50 MHz substitute. | Select only if system requires 156.25 MHz; no electrical or layout change needed beyond frequency validation. |
| Si510-500F-50M000000 | LVDS-output CMOS-based XO in 3.2 mm × 2.5 mm package; 125 fs typical jitter at 50 MHz; ±50 ppm stability over life. | Higher jitter and wider stability spec make it suitable for less demanding applications like industrial control, not PCIe Gen 5+. | Use where cost sensitivity outweighs jitter margin; verify PSRR and start-up time compatibility in target power domain. |
Compared with LMK6DE050000ADLET, the LMK6DE156250ADLET offers identical performance at a different frequency, while the Si510-500F-50M000000 trades 25 fs higher jitter and double the frequency drift for broader vendor availability and lower unit cost in non-critical timing roles.

FAQ
What is the output type and load requirement for LMK6DE050000ADLET?
The LMK6DE050000ADLET provides an LVDS output with a typical differential voltage swing of 350 mV and requires a 100 Ω differential termination across OUTP and OUTN. It drives standard LVDS receivers without external level-shifting and maintains 45–55% duty cycle across temperature and voltage.
Does LMK6DE050000ADLET support frequency adjustment or reprogramming after shipment?
No. The LMK6DE050000ADLET is a factory-programmed fixed-frequency device with no I²C, SPI, or pin-strapping interface. Its 50.000 MHz output, LVDS format, and Pin 1 OE/ST configuration are permanently set during manufacturing and cannot be modified in the field.
What is the start-up time and output enable timing for LMK6DE050000ADLET?
The LMK6DE050000ADLET achieves full output stability within 5 ms of VDD reaching 95% of nominal voltage. When Pin 1 is used as Output Enable, the device enables its LVDS output within 25 µs of OE rising above VIH (1.3 V), and disables within 1 µs of OE falling below VIL (0.6 V).
How does LMK6DE050000ADLET achieve ±25 ppm frequency stability over 10 years?
The LMK6DE050000ADLET achieves ±25 ppm total stability by combining BAW resonator inherent aging resistance (<±1 ppm/yr), factory calibration across voltage and temperature, and integrated compensation circuitry - covering initial tolerance, solder shift, –40°C to +85°C variation, ±5% supply deviation, and 10-year aging at 25°C.
Can LMK6DE050000ADLET operate from both 2.5V and 3.3V supplies interchangeably?
Yes. The LMK6DE050000ADLET is rated for 2.5V–3.3V ±5% operation and maintains full specification compliance across this range - including jitter, output swing, and start-up time - without any configuration change or external components.
