Texas Instruments LMK62A2-150M00SIAT

Overview

LMK62A2-150M00SIAT from Texas Instruments is a factory-programmed, low-jitter LVDS oscillator delivering 150 MHz output with ±50 ppm total frequency tolerance, 150 fs RMS phase jitter (12 kHz–20 MHz), and robust –60 dBc PSRR across 50 kHz–1 MHz supply ripple. It operates from a single 3.3-V supply over –40°C to +85°C and targets high-speed FPGA clocking, network line card timing, and storage/SAN reference generation.

For engineers reviewing the LMK62A2-150M00SIAT datasheet, LMK62A2-150M00SIAT pinout, LMK62A2-150M00SIAT application, or LMK62A2-150M00SIAT equivalent, this page delivers verified specifications, package mapping, differential output behavior, industrial-grade stability data, and real-world implementation context for clock-sensitive embedded and infrastructure systems.

Technical Context

The LMK62A2-150M00SIAT integrates a high-performance PLL-based core with internal power conditioning to suppress supply noise, enabling stable 150 MHz LVDS output without external filtering. Its architecture supports fast startup (10 ms) and OE-controlled output enable/disable (50 µs), with differential outputs compliant to LVDS electrical standards including 300–480 mV swing, 107 Ω differential impedance, and 45–55% duty cycle.

Designed as a drop-in replacement for quartz oscillators, it uses a fixed-frequency, pre-programmed configuration-no external programming interface or configuration pins. The device relies on internal trimming and factory calibration to achieve ±50 ppm total tolerance across temperature, voltage, aging, and reflow, eliminating system-level calibration overhead.

FAQ

What is the output format and load requirement for LMK62A2-150M00SIAT?

The device outputs LVDS signals with a nominal differential swing of 390 mV (typical), requiring a 100 Ω Thevenin termination across OUTP and OUTN. Output common-mode voltage is 1.2 V (typical), and differential impedance is 107 Ω. No external resistors are needed beyond the standard 100 Ω termination.

Does LMK62A2-150M00SIAT require external configuration or programming?

No. The LMK62A2-150M00SIAT is factory-programmed to 150 MHz with fixed LVDS output and ±50 ppm tolerance. It has no I²C, SPI, or pin-strapping interface-operation begins automatically after power-up and OE assertion.

How does the OE pin function, and what is its default state?

OE (Pin 1) is an LVCMOS input with internal pulldown. When held low (≤0.6 V), outputs go high-impedance; when pulled high (≥1.4 V), outputs activate. Default state is disabled due to internal pulldown-external 10 kΩ pullup is required for normal operation.

Can LMK62A2-150M00SIAT replace a 5032-package crystal oscillator on an existing PCB?

Yes. Its 5.0 mm × 3.2 mm SIA QFM package matches standard 5032 XO footprints mechanically and electrically. Pinout differs (6-pin vs. 4-pin), but layout adapters exist; verify OE handling and termination match your receiver's LVDS input spec before drop-in use.
