ISP1507A
General Description
The ISP1507 is a Universal Serial Bus (USB) On-The-Go (OTG) transceiver that is fully compliant with Universal Serial Bus Specification Rev. 2.0, On-The-Go Supplement to the USB 2.0 Specification Rev. 1.3 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 HVQFN32 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 portable devices or system ASICs with built-in USB OTG device core
- 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)
- Complete USB OTG physical front-end that supports Host Negotiation Protocol (HNP) and Session Request Protocol (SRP)
- Integrated 5 V charge pump; also supports external charge pump or 5 V VBUS switch
- Complete control over bus resistors
- Data line and VBUS pulsing session request methods
- Integrated VBUS voltage comparators
- Integrated cable (ID) detector
- Highly optimized ULPI-compliant interface
- 60 MHz, 8-bit interface between the core and the transceiver
- Supports 60 MHz output clock configuration
- Integrated Phase-Locked Loop (PLL) supporting one crystal or clock frequency of 19.2 MHz
- Fully programmable ULPI-compliant register set
- Internal Power-on Reset (PoR) circuit
- Flexible system integration and very low current consumption, optimized for portable devices
- Power-supply input range is 3.0 V to 3.6 V
- Internal voltage regulator supplies 3.3 V and 1.8 V
- Supports external VBUS charge pump or 5 V supply: External VBUS source is controlled using the PSW_N pin; open-drain PSW_N allows per-port or ganged power control
Digital FAULT input to monitor the external VBUS supply status - Pin CHIP_SELECT_N 3-states the ULPI interface, allowing bus reuse for other applications
- Supports wide range interfacing I/O voltage of 1.65 V to 3.6 V; separate I/O voltage pins minimize crosstalk
- Typical operating current of 10 mA to 48 mA, depending on the USB speed and bus utilization
- Typical suspend current of 35 µA
- Full industrial grade operating temperature range from –40 °C to +85 °C
- 4 kV ElectroStatic Discharge (ESD) protection at pins DP, DM, ID, VBUS and GND
- Available in a small HVQFN32 (5 mm x 5 mm) Restriction of Hazardous Substances (RoHS) compliant, halogen-free and lead-free package
