1. General description

The ISP1107 is a Universal Serial Bus (USB) transceiver that is fully compliant with the

Universal Serial Bus Speciﬁcation Rev. 1.1

devices such as mobile phones, digital still cameras and personal digital assistants. It allows 1.8 V, 2.5 V and 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 has an integrated 5 V to 3.3 V voltage regulator allowing direct powering from the USB supply V

The ISP1107 can be used as a USB device transceiver or a USB host transceiver. It can transmit and receive serial data at both full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s) data rates. The ISP1107 is compatible with the industry-standard Philips Semiconductors USB transceiver PDIUSBP11A.

[1] Signal levels on D+/D− are determined by other USB devices and external pull-up/down resistors. [2] In ‘suspend’ mode (SUSPND = HIGH) the differential receiver is inactive and output RCV is always

LOW. Out-of-suspend (‘K’) signalling is detected via the single-ended receivers VP and VM.

[3] During suspend, the slew-rate control circuit of low-speed operation is disabled. The D+/D− are still

driven to their intended states, without slew-rate control. This is permitted because driving during suspend is used to signal remote wakeup by driving a ‘K’ signal (one transition from idle to ‘K’ state) for a period of 1 to 15 ms.

7.3 Power supply conﬁgurations

The ISP1107 can be used with different power supply conﬁgurations, which can be changed dynamically. An overview is given in Table 6.

Normal mode — Both V operation, V

is connected to a 5 V source (4.0 to 5.5 V). The internal voltage

CC(5.0)

regulator then produces 3.3 V for the USB connections. For 3.3 V operation, both V

CC(5.0)

and V

are connected to a 3.3 V source (3.0 - 3.6 V). V

reg(3.3)

independently connected to a 1.8 V, 2.5 V or 3.3 V source, depending on the supply voltage of the external circuit.

Disable mode — V

CC(5.0)/Vreg(3.3)

are not connected. In this mode, the D+/D− pins are made three-state and the ISP1107 allows external signals of up to 3.6 V to share the D+/D− lines. The ISP1107’s internal circuits ensure that virtually no current is drawn via the D+/D− lines. The power consumption through pin V

drops to the low-power (suspended) state level. Both the VP and VM pins are

CC(I/O)

driven HIGH to indicate this mode.
