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.

The VSC7640 is a high-performance, four-channel VCSEL driver array

designed to operate up to 3.125 Gbps for use in 10 Gbps Very Short

Reach (VSR) parallel module applications. This device provides four indi-

vidual VCSEL driver channels, a serial programmable interface tempera-

ture sensor for each channel, a temperature sensor, an overcurrent sen-

sor and control for each channel, and monitoring logic for eye safety shut-

down and power-on reset. The VSC7640 is designed to interface to a

four-channel VCSEL array and to work in conjunction with a microcon-

troller. Unlike other competitive solutions the VSC7640 features a program-

mable negative peaking control to compensate for VCSEL slow tail cur-

rents. The VSC7640 is a die-level product that is fully tested at the maximum

operating speed to guarantee performance and module manufacturing

yields.
