Frequently Asked Questions
How many USB ports does TUSB2046IBVF support and at what maximum data rate?
TUSB2046IBVF supports 4 downstream USB ports compliant with USB 1.1 full-speed at 12 Mbps maximum data transfer rate, plus 1.5 Mbps low-speed device compatibility. All 4 ports operate simultaneously, allowing connection of keyboards, mice, barcode scanners, and other USB peripherals to a single upstream host port.
What clock input options does TUSB2046IBVF accept and how does this affect PCB BOM?
TUSB2046IBVF accepts either a 6 MHz crystal connected to its crystal pins or an external 48 MHz clock signal directly. Using a 6 MHz crystal is the lower-cost option since 6 MHz crystals are cheaper and smaller than 48 MHz equivalents, while the direct 48 MHz input suits designs that already have a clock distribution network, eliminating the crystal and its two load capacitors from the BOM.
How does the optional serial EEPROM interface in TUSB2046IBVF benefit OEM hub designs?
The serial EEPROM interface on TUSB2046IBVF allows customers to program a custom 16-bit Vendor ID and 16-bit Product ID, plus hub descriptor strings, without any microcontroller or firmware. This lets OEM manufacturers brand their 4-port USB hub product with proprietary IDs recognized by Windows, Linux, and macOS device managers, critical for certified USB hub products.
What temperature range does TUSB2046IBVF support and which rugged environments suit it?
TUSB2046IBVF is rated for industrial-grade operation across a -40°C to +85°C ambient temperature range. This qualification makes it suitable for factory automation HMI terminals, outdoor kiosk systems, and in-vehicle infotainment hubs where commercial-grade 0°C to 70°C parts would fail to meet the thermal requirements.
