An optical module configured to electrically connect to a host. A linear equalizer performs equalization on a host equalized signal to create a module equalized signal, and a driver configured to present the module equalized signal from the linear equalizer to an optical conversion device at a magnitude suitable for the optical conversion device. An optical conversion device receives the module equalized signal from the driver, converts the module equalized signal to an optical signal, and transmit the optical signal over an optical channel. Also part of the optical module is an interface which communicates supplemental equalizer settings to the host. A memory stores the supplemental equalizer settings which reflect the optical modules effect on a signal passing through the optical module. A controller oversees communication of the supplemental equalizer settings to the host such that the host uses the supplemental equalizer settings to modify host equalizer settings.

Optimal equalization partitioning

A communication interface comprising a host with non-linear equalizers configured to perform non-linear equalization. Also part of the interface is a host to optic module channel electrically connecting the host to an optic module and the optic module. The optic module comprises a transmitter and a receiver. The transmitter includes a linear equalizer and an electrical to optical module configured to convert the equalized signal from the driver to an optical signal, and transmit the optical signal over a fiber optic cable, such that the transmitter does not perform non-linear processing. The receiver includes a photodetector, configured to convert the received optic signal to a received electrical signal, and a linear amplifier configured to perform linear amplification on the received electrical signal. A driver sends the amplified received signal over an optic module to host channel, such that the receive does not perform non-linear processing.

A package and integrated circuit assembly is configured to perform signal conditioning on a signal. The assembly includes a line card having line card contacts that correspond to conductors in the line card connector. Two or more integrated circuits are configured to perform signal conditioning on the signal and the two or more integrated circuits are configured within a package into at least a first row and a second row on the package. The package includes a grid array of bonding pads to electrically connect to the two or more integrated circuits through bond wires or down bonds such that the structure of the grid array corresponds in physical arrangement or bond pad pitch to the line card contacts. This assembly also includes an electrical connection from the two or more integrated circuits to the line card through the package.

High speed signal conditioning package

An integrated system for adaptive equalization and jitter reduction of a video signal that includes an adaptive equalizer and a jitter cleaner located on one integrated circuit within a single package. An adaptive equalizer applies frequency specific signal modification to the received signal. A bit rate detector determines a bit rate of the video signal or the equalized signal. The jitter cleaner couples to the adaptive equalizer output and processes the equalized signal to reduce jitter in the equalized signal. A multiplexer receives the equalized signal and the jitter cleaner output and, responsive to a control signal, outputs either the equalized signal or the jitter cleaner output signal. A status monitor may optionally be included to compare the detected bit rate to a bit rate threshold, and a responsive to the comparing activate or deactivate the jitter cleaner and output either the equalized signal or jitter cleaner output.
