1. An apparatus comprising:
- one or more non-clock and data recovery (CDR) components comprising one or more amplifiers on a substrate;
a signal generator on the substrate and configured to provide a test signal for testing one or more components selected from a group consisting of the one or more non-CDR components and a CDR component on the substrate; and
the CDR component on the substrate and coupled to the one or more non-CDR components, wherein the CDR component is;
configured to recover clock data from an electrical signal received by the the one or more non-CDR components, andconfigured to generate a recovered data signal based on the electrical signal and the clock data.
