Clock generator with 50 fs rms jitter at 312.5-MHz output frequency

Texas Instruments Incorporated has introduced LMK03806 clock generator with sub-50 femtosecond (fs) rms jitter at 312.5-MHz output frequency. LMK03806 provides designers to synthesize their required clock frequencies from a single low-cost crystal, as per TI.

The LMK03806 is said to simplify timing architectures in wired and optical communications line cards by simultaneously synthesizing seven independent frequencies on 14 outputs and with an output frequency that spans 2.37 MHz to 2.6 GHz, the LMK03806 provides clocking support for all of the components on a typical line card, explains TI.

Other key features and benefits of the LMK03806 as per TI include:
High-frequency voltage-controlled oscillator (VCO) and programmable output dividers: Simplifies timing design by simultaneously generating a wide array of common frequencies.
Programmable LVDS, LVPECL and LVCMOS: Each output clock is independently configurable, eliminating the need for level translators and fanout buffers.
Crystal interface: Allows designer to use a low-cost crystal for simultaneously generating multiple clocks.
Its extreme flexibility allows clock designers to address several additional markets, including wireless infrastructure and industrial applications.

Availability, packaging and pricing:
The LMK03806 is available today in a 9-mm x 9-mm, 64-pin LLP package for a suggested retail price of $7.95 in 1,000-unit quantities. Also available today, the LMK00301 is supplied in a 7-mm x 7-mm, 48-pin LLP package for a suggested retail price of $2.95 in 1,000-unit quantities.
