ISP1103
Universal Serial Bus transceiver
Rev. 01 鈥?4 October 1999
Preliminary speci鏗乧ation
1. General description
The ISP1103 is a single-chip generic Universal Serial Bus (USB) transceiver that is
fully compliant with the
Universal Serial Bus Speci鏗乧ation Rev. 1.1.
It allows 3.3 V
USB Application Speci鏗乧 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
鈥榮uspend鈥?mode operation. The ISP1103 operates on a 3.3 V supply voltage.
The pin con鏗乬uration conforms to the 鈥楽erial Interface Engine鈥?from the Universal
Serial Bus Implementers Forum (USB-IF). The ISP1103 allows for both the 鈥楿SB-IF
Standard Data Interface鈥?and the 鈥楶hilips Encoded Data Interface鈥? The ISP1103 is
fully pin compatible with the industry-standard Philips Semiconductors USB
transceiver PDIUSBP11A.
