Nanotech Semiconductor, a mixed-signal fabless IC company has introduced pure-CMOS ICs for Gigabit Ethernet optical fibre-based communications.  

Both ICs support both 3.3V and 5V supplies, with 34mA total current consumption including output loading. The ICs feature a glitch-free loss of signal status output and signal squelch function.

Typical output rise & fall times of 100ps and 2mV sensitivity easily meet all applications requirements, and exceptional 3kV ESD immunity on all pins is testament to the ruggedness of modern CMOS processes.

“Like our earlier MOST, Fast-Ethernet, OC-3 and OC-12 chipsets, creating a pure-CMOS chipset for Gigabit Ethernet is the sure fire way to bring the highest quality, yet lowest cost solution to the market,” said Gary Steele, CEO of Bristol-based Nanotech.

Together with the now industry-standard NT24L50 1.25Gbit/s TIA and the NT22L31 Laser Driver, this completes the pure-CMOS 3-chip set for 1.25Gbit/s applications.

The NT24L7x, manufactured in low cost standard 0.18µm CMOS, are available in QSOP16 [24L71] and MSOP10 [24L73] packages, and are pin-compatible with ICs manufactured by Maxim, Micrel and iCreate.
