ISP1507C
General Description
The ISP1507 is a Universal Serial Bus (USB) high-speed host and peripheral transceiver that is fully compliant with Universal Serial Bus Specification Rev. 2.0 and UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.
The ISP1507 can transmit and receive USB data at high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s), and provides a pin-optimized, physical layer front-end attachment to USB host, peripheral and OTG devices.
It is ideal for use in portable electronic devices, such as mobile phones, digital still cameras, digital video cameras, Personal Digital Assistants (PDAs) and digital audio players. It allows USB Application-Specific Integrated Circuits (ASICs), Programmable Logic Devices (PLDs) and any system chip set to interface with the physical layer of the USB through a 12-pin interface.
The ISP1507 can interface to the link with digital I/O voltages in the range of 1.65 V to 3.6 V.
The ISP1507 is available in HVQFN24 package.
Key Features
- Fully complies with:
- Universal Serial Bus Specification Rev. 2.0
- On-The-Go Supplement to the USB 2.0 Specification Rev. 1.3
- UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1
- Interfaces to host, peripheral and OTG device cores; optimized for stand-alone and embedded host applications with an external VBUS supply; stand-alone peripheral cores, and Session Request Protocol (SRP)-capable peripheral cores
- Complete Hi-Speed USB physical front-end solution that supports high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s)
- Integrated 45 ohm ± 10 % high-speed termination resistors, 1.5 kohm ±5 % full-speed device pull-up resistor, and 15 kohm ± 5 % host termination resistors
- Integrated parallel-to-serial and serial-to-parallel converters to transmit and receive
- USB clock and data recovery to receive USB data up to ±500 ppm
- Insertion of stuff bits during transmit and discarding of stuff bits during receive
- Non-Return-to-Zero Inverted (NRZI) encoding and decoding
- Supports bus reset, suspend, resume and high-speed detection handshake (chirp)
- Supports SRP for reduced power consumption
- Complete control over bus resistors
- Data line and VBUS pulsing session request methods
- Integrated VBUS voltage comparators
- Highly optimized ULPI-compliant interface
-
- 60 MHz, 8-bit interface between the core and the transceiver
