CY7C65630-56LTXC Electronic Components

CY7C65630-56LTXC Electronic Components belongs to USB interface IC.EZ-USB HX2LP™ is Cypress’s next generation family of high-performance, low-power USB 2.0 hub controllers. HX2LP is an ultra low power single chip USB 2.0 hub controller with integrated upstream and downstream transceivers, a USB serial interface engine (SIE), USB hub control and repeater logic, and TT logic. 

Cypress has also integrated many of the external passive components, such as pull-up and pull-down resistors, reducing the overall bill of materials required to implement a hub design. The HX2LP portfolio consists of:

-CY7C65630: 4-port/single transaction translator
-CY7C65620: 2-port/single transaction translator

Product Description

USB Serial Interface Engine:The serial interface engine (SIE) allows the CY7C65620/CY7C65630 to communicate with the USB host. The SIE handles the following USB activities independently of the Hub Control Block.

Hub Repeater：The hub repeater manages the connectivity between upstream and downstream facing ports that are operating at the same speed. It supports full- or low-speed connectivity and high-speed connectivity. According to the USB 2.0 specification, the HUB Repeater provides the following functions: ① Sets up and tears down connectivity on packet boundaries ② Ensures orderly entry into and out of the suspend state, including proper handling of remote wakeups.

Product Applications

Typical applications for the HX2LP device family are: 
-Standalone hubs 
-Motherboard hubs 
-Monitor hubs  
-Advanced port replicators 
-Docking stations 
-Split-PC designs 
-External personal storage drives 
-Keyboard hubs

Functional Overview 

The Cypress CY7C65620/CY7C65630 USB 2.0 Hubs are high-performance, low system cost solutions for USB. The CY7C65620/CY7C65630 USB 2.0 Hubs integrate 1.5 k upstream pull-up resistors for full-speed operation and all downstream 15 k pull-down resistors and series termination resistors on all upstream and downstream D+ and D– pins. This results in optimization of system costs by providing built-in support for the USB 2.0 specification.
