VSC7650

The VSC7650 and VSC7651 are high-performance, four-channel receiver arrays designed to operate up to 3.125 Gbps for use in 10 Gbps Very Short Reach (VSR) parallel module or 10GBASE-LX4 Coarse Wavelength Division Multiplexing (CWDM) applications. Each channel includes a bias filter, a transimpedance amplifier, a limiting amplifier, an output driver, and Loss of Signal (LOS) detect circuitry. Signal monitors for each channel facilitate optical alignment. The VSC7650 and VSC7651 are die-level products that are fully tested at the maximum operating speed to guarantee performance and improve module manufacturing yields. The VSC7650 and VSC7651 are pin and functional compatible; the designer has the flexibility to choose the output level version as required by system architecture and performance.
