Abstract
A Tx IC and an Rx IC that use different supply voltages are mounted on a circuit board and interfaced via traces of the board. The configuration of the Tx IC is such that DC decoupling is provided between the ICs while also preventing inadvertent turn-on of the ESD diodes of the Rx IC. These features make it possible to provide DC decoupling between high-performance Tx ICs that use relatively high supply voltages and Rx ICs that use relatively low supply voltages without the need for AC coupling capacitors and while also preventing ESD protection of the Rx IC from being degraded.
