HMC914LP4E

HMC914LP4E v03.1012 12.5 Gbps LIMITING AMPLIFIER w/ LOSS OF SIGNAL FEATURE limiting amplifiers - smt Typical Applications The HMC914LP4E is ideal for: SONET/SDH-Based Transmission Systems OC-192 Fiber Optic Modules 10 Gigabit Ethernet 8x and 10x Fiber Channel Wideband RF Gain Block Features Supports Data Rates up to 12.5 Gbps Differential Small Signal Gain: 32 dB Programmable Loss-of-Signal Detection (LOS) Automatic Output Disable Mode Adjustable Output Voltage Swing up to 750 mVp-p Differential Integrated DC Offset Correction Received Signal Strength Indicator (RSSI) Output 24 Lead Plastic 4x4mm SMT Package: 16mm² Functional Diagram General Description HMC914LP4E is a limiting amplifier designed to support data transmission rates up to 12.5 Gbps. The amplifier can operate over a wide range of input voltage levels and provides constant-level differential output swing. HMC914LP4E features a loss of signal (LOS) indicator output where the input signal amplitude threshold level can be adjusted using the LOSTH pin. HMC914LP4E also features an output level control pin, VAC, which allows for loss compensation or for output signal level optimization. Differential output signal swing can be adjusted up to 750 mVp-p. An integrated DC offset compensation is also provided on chip. The HMC914LP4E provides an analog RSSI output voltage which is proportional to input signal amplitude. All single-ended input signals are terminated with 50 ohms to +3.3V on-chip, and ma...
