The ONET1191P is a high-speed, 3.3-V limiting amplifier for copper-cable and fiber-optic applications with data

rates up to 11.3 Gbps.

This device provides a gain of about 40 dB which ensures a fully differential output swing for input signals as low

as 5 mV

. The output amplitude can be adjusted from 400 mV

to 700 mV

. Loss-of-signal detection and

output disable are also provided.

The part is available in a small-footprint, 3-mm × 3-mm, 16-pin QFN package, typically dissipates less than 110

mW, and is characterized for operation from –40 ° C to 85 ° C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.

ONET1191P www.ti.com SLLS754 – SEPTEMBER 2006 BLOCK DIAGRAM A simplified block diagram of the ONET1191P is shown in Figure 1. This compact, low-power, 11.3-Gbps limiting amplifier consists of a high-speed data path with offset cancellation (dc feedback), a loss-of-signal detection block using two peak detectors, and a band-gap voltage reference and bias current generation block.

ONET1191P www.ti.com SLLS754 – SEPTEMBER 2006 BAND-GAP VOLTAGE AND BIAS GENERATION The ONET1191P limiting amplifier is supplied by a single 3.3-V supply voltage connected to the VCC pins. This voltage is referred to ground (GND). On-chip band-gap voltage circuitry generates a reference voltage, independent of supply voltage, from which all other internally required voltages and bias currents are derived.
