M02049

1 Gbps to 4.3 Gbps, 3.3 or 5 V Post-Amplifier

Overview

Description

The M02049/50 are integrated high-gain limiting amplifiers. Featuring CML outputs, the M02049 is usable in applications to 4.3 Gbps while the M2050 features PECL outputs and is intended for use in applications to 2.5 Gbps. Full output swing is achieved even at minimum input sensitivity. The M02049/50 can operate with a 3.3V or 5V supply. Rate select is supported for SFP applications and/or to achieve optimum sensitivity at data rates ≤ 1.25 Gbps. When rate select is high, optimum sensitivity is achieved at 2.5 Gbps and operation up to 4.3 Gbps (M02049) is possible with reduced sensitivity. The M02049/50 also includes two analog RSSI outputs proportional to either the average or peak-to-peak input signal and a programmable signal-level detector allowing the user to set thresholds at which the logic outputs are enabled.
