LG1605DXB General Description
The amplifier has a virtually constant output delay for input signal levels, varying across three decades. As a result, the device has very low amplitude-to-phase conversion, which makes it ultimately suitable for applications in highly sensitive fiber-optic systems. Although the amplifier is most sensitive when the input is ac coupled (see Figure 3), a low offset (<25 mV) and a large common-mode input range of 2 V make it useful in applications that require a high-speed comparator as well.
A unique input coupling arrangement allows for a frequency response down into the low kHz range while using coupling capacitors that are small enough to maintain a good input return loss at high frequencies.
The outputs, when ac coupled, provide a good RF termination up to very high frequencies. The associatedability to absorb reflections returning from the receiving
end is essential for preventing intersymbol interference
in fiber-optic systems.
The amplifier is a natural step-up interface between receivers, such as the Lucent Technologies Microeletronics Group Optoelectronics unit 1319 and regenerators like the Lucent Technologies Microelectronics Group LG1600. The referred wideband input noise (168 Vrms typical) allows for a <1e9 bit error rate (BER) for inputs down to 2 mVp-p (S/N ratio of 21.5 dB).
In SAW based clock recovery systems, with clock frequencies as high as 2.5 GHz, the device can provide a clock-limiting function in systems.
The LG1605DXB is available in a hermetically sealed, 16-lead, glass-metal surface-mount package and uses a standard ECL supply.
LG1605DXB Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent or latent damage to the device.
These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
