1. Overview
This document serves as a reference for designing with the GS1572. It uses the GS1572
evaluation board as a guide. The document is separated into two main sections:
1. Recommended PCB layout practices when designing with the GS1572.
2. A user’s guide to the GS1572 evaluation board, including information on how to use
the board, and detailed schematic and board layout information.
An example of a board design including the GS1572 is shown below. A 10-bit or 20-bit
signal at HD or SD rates must be supplied, along with a parallel clock. The serialized
output is driven by an internal cable driver. The output is fed to BNC’s.
The GS1572 also requires the external GO1555 VCO.
