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 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.

. It allows 3.3 V

2. Features

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.

MODE 1 I driver interface selection input (Schmitt trigger):

LOW: Philips Encoded Data Interface (pins VO, FSE0) HIGH: USB-IF Standard Data Interface (pins VPO, VMO);

pulled HIGH by an internal pull-up transistor, if left ﬂoating

OE 2 I output enable input (Schmitt trigger, active LOW); enables the

transceiver to transmit data on the bus

RCV 3 O differential data receiver output (CMOS level); driven HIGH

when input SUSPND is HIGH; the output state of RCV is preserved and stable during an SE0 condition

VP 4 O single-ended D+ receiver output (CMOS level); used for

external detection of single-ended zero (SE0), error conditions, speed of connected device

VM 5 O single-ended D− receiver output (CMOS level); used for

external detection of single-ended zero (SE0), error conditions, speed of connected device

SUSPND 6 I suspend input (Schmitt trigger); a HIGH level enables

low-power state while the USB bus is inactive and drives

output RCV to a HIGH level GND 7 - ground supply n.c. 8 - not connected SPEED 9 I speed selection input (Schmitt trigger); adjusts the slew rate

of differential data outputs D+ and D− according to the

transmission speed:

LOW: low-speed (1.5 Mbit/s) HIGH: full-speed (12 Mbit/s)

[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.
