MAX3262

MAX3262 19-0324; Rev 2; 12/97 1Gbps, High-Speed Limiting Amplifier with Chatter-Free Loss-of-Signal Detection ________________General Description 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. ________________________Applications 1062Mbps Fibre Channel 622Mbps SONET ____________________________Features o 900MHz Bandwidth o 48dB Maximum Gain o Chatter-Free LOS o Programmable LOS Threshold o Single +5V ...
