NXPISP1504ULPI收发器解决方案

NXP公司的ISP1504是8位双向ULPI收发器,能为ASIC和FPGA器件提供高速USB模拟前端解决方案,从而实现高速USB主机接口,外设接口和OTG接口.ISP1504评估板为设计者提供了评估ISP1504的特性,以及进行系统级的确认和测试.本文介绍了ISP1504评估板的主要性能,连接器和详细的应用电路图以及所用的元器件清单(BOM).

The ISP1504 is an 8-bit bidirectional UTMI+ Low Pin Interface (ULPI) transceiver, which provides a Hi-Speed Universal Serial Bus (USB) analog front-end solution to Application-Specific Integrated Circuits (ASICs) and Field Programmable Gate Arrays (FPGAs) to implement as a Hi-Speed USB host, peripheral or OTG device.

The ISP1504 evaluation (eval) board allows designers to evaluate the features of the ISP1504, and conduct system-level validation and testing. The eval board interfaces to the link through a 100-pin Transceiver and Macrocell Tester (T&MT) connector that complies with USB 2.0 Transceiver and Macrocell Tester (T&MT) Interface Specification Ver. 1.2.

Fig 1 shows the ISP1504 eval board.



1.功能:
The ISP1504 is fully compliant with Universal Serial Bus Specification Rev. 2.0, UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1 and On-The-Go Supplement to the USB 2.0 Specification Rev. 1.0a.

The T&MT connector interface is fully compliant with USB 2.0 Transceiver and Macrocell Tester (T&MT) Interface Specification Ver. 1.2.

The VBUS power can be supplied either by the on-chip charge pump or by the on-board power switch.

Configurable active-HIGH or active-LOW reset signal from the link.

Adjustable VCC voltage when powered by the 5 V DC power supply.
Configurable CHIP_SEL_N signal.
Flexible clock source for the ISP1504: on-board crystal, 60 MHz input clock or square wave clock driven into the XTAL1 input.
