ISP1103

Universal Serial Bus transceiver

Rev. 01 — 4 October 1999

Preliminary specification

1. 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.

6.1Function selection

Table 3:	Function table
SUSPND		OE		D+/D−	RCV	VP/VM	Function
L		L		driving	active	active	normal driving
							(differential receiver active)
L		H		receiving [1]	active	active	receiving
H		L		driving	inactive [2]	active	driving during ‘suspend’
							(differential receiver inactive)
H		H		high-Z [1]	inactive [2]	active	low-power state

[1]Signal levels on D+/D− are determined by other USB devices and external pull-up/down resistors.

[2]In ‘suspend’ mode (SUSPND = H) the differential receiver is inactive and output RCV is always HIGH. Out-of-suspend (‘K’) signalling is detected via the single-ended receivers VP and VM.

[1]RCV* denotes the signal level on output RCV just before SE0 state occurs. This level is kept stable during the SE0 period.
