  • Simple, flexible customisation
  • Reduced design cycle time
  • Integrated on chip LDOs
  • I2C control, integrated EEPROM
Texas Instruments LMK61xxx Ultra Low Jitter Differential Oscillator family

Product Description

An industry-leading addition to the ultra-low jitter oscillator family, the LMK61xx provides 100fs rms jitter performance (12K-20MHz), meeting the jitter requirements of the newest standards to offer future proof design with plenty of margin.

Integrated multi write EEPROM memory enables customised start-up frequency, while a pin strap device enables AVL consolidation. Fine and coarse frequency margining enables quick and easy in-system validation with same hardware design for both evaluation and production.

The LMK61xx eliminates the problem of non-standard frequencies proving difficult to source by using one common XTAL + PLL architecture to provide supply chain robustness and rapid turn around for samples and production orders. Integrated LDOs provide robust supply noise immunity.

Typical applications include switches, routers, telecom/datacom line cards, servers, storage/SAN, medical imaging and test & measurement.

Industry’s lowest jitter

90 fs typical root mean square (RMS) jitter performance, 12 kHz-20 MHz, is less than half of competing oscillators, improving reliability and system margin in communications, test and measurement, and medical applications.

Flexibility and easy customization

The family of 11 oscillators includes programmable, pin- selectable and fixed-frequency devices, offering flexible low-voltage pseudo emitter-coupled logic (LVPECL), low-voltage differential signaling (LVDS) and high-speed current steering logic (HCSL)output formats and frequency ranging from 10 MHz to 1 GHz with a variety of options to meet designers’ needs.

Reduced design cycle time

Glitchless fine/coarse frequency margining enables designers to ease compliance and stress testing of their systems during design verification of prototypes.
