The CY7C65640A-LTXC is a high speed USB Hub Controller integrates 1.5k up-stream pull-up resistors for full speed operation and all downstream 15k pull-down resistors and series termination resistors on all up-stream and down-stream D+ and D- pins. TetraHub? Being a fixed-function USB device, there is no risk or added engineering effort required for firmware development. The developer does not need to write any firmware for their design.
Four down-stream ports
Multiple transaction translators - one per downstream port for maximum performance
VID, PID and DID configured from external SPI EEPROM
Integrated up-stream pull-up resistor
Integrated down-stream pull-down resistors for all down-stream ports
Integrated up-stream and down-stream series termination resistors
