General description
The ISP1103 is a single-chip generic Universal Serial Bus (USB) transceiver that is fully compliant with the Universal Serial Bus Specification Rev.
1.
1.
It allows 3.
3 V USB Application Specific ICs (ASICs) and Programmable Logic Devices (PLDs) to interface with the physical layer of the Universal Serial Bus.
It supports transmitting and receiving serial data at both full-speed (12 Mbit/s) and low-speed (1.
5 Mbit/s) data rates.
It also supports the low-power single-ended input receiver interface in ‘suspend’ mode operation.
The ISP1103 operates on a 3.
3 V supply voltage.
The pin configuration conforms to the ‘Serial Interface Engine’ from the Universal Serial Bus Implementers Forum (USB-IF).
The ISP1103 allows for both the ‘USB-IF Standard Data Interface’ and the ‘Philips Encoded Data Interface’.
The ISP1103 is fully pin compatible with the industry-standard Philips Semiconductors USB transceiver PDIUSBP11A.
