ISP1102
Advanced Universal Serial Bus transceiver
Rev. 03 — 02 September 2003
Product data
1. General description
The ISP1102 Universal Serial Bus (USB) transceiver is fully compliant with the
Universal Serial Bus Specification Rev. 2.0. The ISP1102 can transmit and receive
USB data at full-speed (12 Mbit/s).
The transceiver allows USB Application Specific ICs (ASICs) and Programmable
Logic Devices (PLDs) with power supply voltages from 1.65 to 3.6 V to interface with
the physical layer of the USB. The transceiver has an integrated 5 V-to-3.3 V voltage
regulator for direct powering via the USB supply line VBUS. The transceiver has an
integrated voltage detector to detect the presence of the VBUS voltage (VCC(5.0)).
When VCC(5.0) or Vreg(3.3) is lost, the D+ and D− pins can be shared with other serial
protocols.
The transceiver is a bi-directional differential interface and is available in HBCC16
and HVQFN14 packages.
The transceiver is ideal for use in portable electronic devices, such as mobile phones,
digital still cameras, personal digital assistants and information appliances.

[1] Signal levels on the D+ and D− pins are determined by other USB devices and external pull-up or
pull-down resistors.
[2] In the suspend mode (SUSPND = HIGH), the differential receiver is inactive and the output RCV is
always LOW. Out-of-suspend (K) signalling is detected via the single-ended receivers VP/VPO and
VM/VMO.

[1] RCV* denotes the signal level on output RCV just before the SE0 state occurs. This level is stable
during the SE0 period.
7.3 Power supply configurations
The ISP1102 can be used with different power supply configurations, which can be
changed dynamically. Table 7 provides an overview of the power supply
configurations.
Normal mode — VCC(I/O) is connected. VCC(5.0) is connected only, or VCC(5.0) and
Vreg(3.3) are connected.
For 5 V operation, VCC(5.0) is connected to a 5 V source (4.0 to 5.5 V). The internal
voltage regulator then produces 3.3 V for the USB connections.
