Easy customization and system-level feature integration

Texas Instruments (TI) (NASDAQ: TXN) today announced the introduction of a family of programmable, pin-selectable, fixed-frequency differential oscillators. The new LMK61xx series delivers the industry's lowest jitter of 90 femtoseconds (fs) in a 7 mm x 5 mm footprint, optimizing signal integrity and reducing data transmission errors in performance-critical applications. The devices also offer easy customization and frequency margining capabilities, and support multiple frequencies with a single device, making them ideal for field-programmable gate arrays (FPGAs), analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and high-speed serial link clocking.

Key features and benefits of the LMK61xx oscillators include: a rated root-mean-square (RMS) jitter performance of 90 fs from 12 kHz to 20 MHz, which is less than half that of competing oscillators, improving reliability and system margins in communications, test and measurement, and medical equipment.



This family of 11 oscillators includes programmable, pin-selectable, and fixed-frequency products, supporting LVPECL (low-voltage pseudo emitter-coupled logic), LVDS (low-voltage differential signaling), and HCSL (high-speed current-steering logic) output formats and a frequency range from 10MHz to 1GHz. We also offer a variety of options to meet the diverse needs of developers, including:

The programmable device offers maximum flexibility with an I2C interface as well as an on-chip electrically erasable programmable read-only memory (EEPROM) capable of 100 write cycles, allowing for easy customization of the startup frequency.

It provides glitchless fine/coarse frequency margining capabilities that enable developers to simplify stress and acceptance testing during design verification and process validation (DVT/PVT) of prototypes.
