  Compared with common multi-chip stacking solutions, PEC-645W is optimized for KVM applications. A single chip integrates the main functional modules of USB2.0 high-speed KVM and streamlines the peripherals. Provide highly integrated and flexible solutions for quickly building high-performance, differentiated KVM products.
  PEC-645W has built-in 4 USB combo device controllers, 8 high-speed USB PHYs and signal switching matrix. Each USB combination device consists of a high-speed 4-port USB HUB and 3 virtual sub-devices. The HUB is connected to 4 external downlink ports through the on-chip matrix. A single chip can support a total of 28 USB devices. The solution does not require an external HUB chip, does not require an ana-log switch to switch USB, supports mixed insertion of USB devices, and has no device type restrictions.
