Product data
1. General description
The ISP1102 Universal Serial Bus (USB) transceiver is fully compliant with the
Universal Serial Bus Speci鏗乧ation Rev. 2.0.
The ISP1102 can transmit and receive
USB data at full-speed (12 Mbit/s).
The transceiver allows USB Application Speci鏗乧 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 V
BUS
. The transceiver has an
integrated voltage detector to detect the presence of the V
BUS
voltage (V
CC(5.0)
).
When V
CC(5.0)
or V
reg(3.3)
is lost, the D+ and D鈭?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.
