Overview
JMB368 is a single chip, 1-lane PCI Express to 1-port PATA Host Controller. It is designed to provide better PATA extension and compatibility, especially for chipsets without PATA. For these chipsets with only one PATA interface, JMB368 also provides a feature-up for Legacy IDE device supporting. It features PCI Express bus interface to lower pin count as possible. JMB368 supports PCI Express trace length can be up to 12” (30.48cm). Although the maximum length is up to 12 inch, the trace length is as short as possible on real application. JMB368 supports PATA trace can be up to 10” (25.4cm). Although the maximum length is up to 10 inch, the trace length is as short as possible on real application. PATA of JMB368 supports up to UDMA6. Serial damping resistors are necessary to keep UDMA performance. Please reference JMB368 Application Schematic in detail. Also, place these serial resistors within 0.5 inch of Host IDE Connector sid
