Hi-Speed Universal Serial Bus PCI Host Controller - Application: PC motherboard, notebook, PCI host add-on card, portable consumer, home entertaintment ; Bus interface: USB at HS (480 Mbit/s), FS (12 Mbit/s) and LS (1.5 Mbit/s) data rates, direct I/F to any 32-bit, 33 MHz I/F ; Downstream ports: 2 ; Features: integrated one Original USB-OHCI and one Hi-Speed USB-EHCI host controllers ; Operating/supply voltage (MAX.-Vcc,Vp,VDD): core 1.8 V, dual power supply 3.6 V V_aux, V_cc V; Other features: EHCI 1.0 spec
The ISP1564ET supports cable lengths up to 3 meters, but this can vary depending on the specific application and signal quality.
To implement hot-swapping, you need to use an external power switch and a voltage supervisor to ensure that the VBUS is only applied when the device is fully powered up. You should also follow the USB specification guidelines for hot-swapping.
No, the ISP1564ET is specifically designed for USB interfaces and is not compatible with other interfaces like I2C or SPI. It's a USB transceiver, not a general-purpose interface chip.
The ISP1564ET has built-in power management features, including suspend and resume modes. You can use the chip's internal registers to control power management, or use an external power management IC to handle power switching and voltage regulation.
No, the ISP1564ET is only compatible with USB 2.0 and lower speeds. If you need to support higher speeds, you'll need to use a different chip, such as the ISP1565 or ISP1761.
