Texas Instruments LMK6PE100000ADLER

Overview

LMK6PE100000ADLER from Texas Instruments is a factory-programmed, ultra-low-jitter LVPECL oscillator delivering 100 MHz fixed-frequency output with ±25 ppm total frequency stability over –40°C to 85°C, 2.5V–3.3V supply, and integrated BAW resonator. It serves as a high-precision reference clock for PCIe Gen 7–compliant SERDES in optical transport and data center line cards.

For engineers reviewing the LMK6PE100000ADLER datasheet, LMK6PE100000ADLER pinout, LMK6PE100000ADLER application, or LMK6PE100000ADLER equivalent, key selection criteria include RMS jitter ≤125 fs (12 kHz–20 MHz), LVPECL output compliance, DLE 3.2 mm × 2.5 mm package, OE/ST pin configuration, and PCIe Gen 7 SRNS jitter <34 fs at 100 MHz.

Technical Context

The LMK6PE100000ADLER implements a Bulk-Acoustic Wave (BAW) resonator co-integrated with a high-performance fractional divider and LVPECL output driver. Its architecture eliminates external crystal components while maintaining sub-125 fs RMS jitter at 100 MHz under industrial temperature and voltage variation.

It features an integrated LDO with –72 dBc PSRR at 500 kHz, enabling robust operation in noisy power environments, and supports Output Enable (Pin 1, active-high) for dynamic clock gating in low-power system states.

FAQ

What is the RMS jitter specification for LMK6PE100000ADLER at 100 MHz?

The LMK6PE100000ADLER has a maximum RMS jitter of 125 fs over the 12 kHz–20 MHz integration bandwidth at 100 MHz output, with typical performance at 100 fs. This value is measured under recommended operating conditions (VDD = 3.3 V, TA = 25°C) and is validated per TI's SNAS826G datasheet. The LMK6PE100000ADLER achieves this using its integrated BAW resonator and low-noise fractional divider architecture.

Does LMK6PE100000ADLER support PCIe Gen 7 compliance?

Yes, the LMK6PE100000ADLER meets PCIe Gen 7 requirements: its measured SRNS jitter is 0.034 ps (34 fs) and common-clock jitter is 0.028 ps (28 fs) at 100 MHz, both well below the Gen 7 limits of 67 fs and 100 fs respectively. These values are confirmed in TI's characterization data for the LMK6P family and apply directly to the LMK6PE100000ADLER variant.

What is the function of Pin 1 on LMK6PE100000ADLER?

Pin 1 on the LMK6PE100000ADLER is configured as Output Enable (OE), active-high. When driven to VIH (≥1.3 V), the LVPECL outputs (OUTP/OUTN) are enabled; when pulled to GND or left floating (NC), outputs are disabled. This pin is not used for standby mode in this variant. The LMK6PE100000ADLER datasheet specifies OE functionality exclusively for Pin 1, consistent with its "E" suffix in the part number.

What package type and dimensions does LMK6PE100000ADLER use?

The LMK6PE100000ADLER uses the VSON DLE-6 package: 3.2 mm × 2.5 mm footprint, 6-pin, exposed pad optional, compliant with JEDEC MO-220. It is distinct from the smaller DLF-6 (2.5 mm × 2.0 mm) variant and shares mechanical compatibility with other LMK6P/D/H devices in DLE format. The package is rated MSL1 and supports standard reflow profiles.

Can LMK6PE100000ADLER operate at 1.8 V supply voltage?

No, the LMK6PE100000ADLER is specified only for 2.5 V–3.3 V ±5% operation, as indicated by the "A" suffix in its part number (voltage/temperature rating code). Devices supporting 1.8 V have "B" or "D" suffixes (e.g., LMK6PBxxx). Attempting 1.8 V operation on LMK6PE100000ADLER may result in failure to start up or degraded jitter performance, and is outside the manufacturer's recommended operating conditions.
