This document is the user guide for the EV-TD12x-PCI evaluation board by Oxford Semiconductor, Inc. It describes the features and characteristics of the evaluation board.
This guide documents the EV‑TD12x‑PCI evaluation board, which combines an EVB12x board (EVB122 or EVB124) with a PCI104 bridge board. It explains how the board enables evaluation of the TD122 and TD124 USB host controllers in a standard PCI‑based computer.
The manual covers hardware operation, PCI104 bridge configuration, schematics, ordering information, and contact details for Oxford Semiconductor. It also references the detailed technical manuals for the TD122 and TD124 devices.
| PCI104 bridge chip | PCI9030 |
|---|---|
| Bridge board speed | 33 MHz, 32 bit |
| USB host ports (EVB122) | 2 ports |
| USB host ports (EVB124) | 4 ports |
| Physical size | double‑width, approx. 3 cm thick |
| PCI bus signal handling | Power and control signals maintained by bridge chip |
The EVB122 version has 2 USB host ports, while the EVB124 version has 4 USB host ports.
It uses the PCI9030 PCI bridge chip to connect the PCI bus to the TD122 or TD124 controller.
The board is a double‑width PCI card, approximately 3 cm thick, occupying one PCI slot.
