Card Clock Architecture
The following figure provides an overview of the Card Clock Architecture of SharpMedia PCIE-
8120.
A synchronous clocking scheme is used for the DSP building blocks to allow for task distribution
over several DSPs. All other components have individual clocking sources.
Oscillators are EPSON SG-210 or equivalent types, +/-50ppm tolerance.
Resonators are EPSON FA238 or equivalent types, +/-23ppm tolerance.
Clock buffer device is TI CDCLVC1112.
B.5
Ethernet NIC
The SharpMedia PCIE-8120 uses Intel 82580EB/DB Gigabit Ethernet Controller to implement
PCI Express connectivity and thereby provides access for the Host system towards the card's
resources. This device supports up to four Ethernet ports with integrated MAC units and
SGMII/SerDes interface. The ports are connected to the Ethernet switch unit on the card. Also,
