The MAX3262 limiting amplifier with its high gain and wide bandwidth is ideal for use as a post amplifier in fiber-optic receivers with data rates up to 1Gbps. The amplifier's gain can be adjusted between 33dB and 48dB. At maximum gain, signals as small as 6mVp-p can be amplified to drive devices with PECL inputs. The MAX3262 has complementary loss-of-signal outputs for interfacing with open-fiber-control (OFC) circuitry. These outputs can be programmed to assert with input levels between 9mVp-p and 48mVp-p. LOS hysteresis for any programmed level is nominally 3.0dB, preserving a balance between noise immunity and dynamic range.
