Freescale Semiconductor User’s Guide PTKIT8102UG Rev. 1, 9/2005 MSC8102 Packet Telephony Farm Card (MSC8102PFC) The MSC8102 packet telephony farm card (MSC8102PFC) is a PCI telephony mezzanine card (PTMC) for evaluating media gateway products. This card is designed around the Star Core™ MSC8102 16-bit fixed-point DSP device. On the MSC8102PFC is a DSP farm consisting of five MSC8102 devices and one MSC8101 device to aggregate the data to/from the DSP farm. Each MSC8102 device has an associated 4M × 32 (16 MB) SDRAM. The MSC8101 aggregator has a separate 2 M × 32 (8 MB) SDRAM. The MSC8102PFC interfaces with a baseboard platform via its PTMC site (see Figure 1). The PTMC is a PCI Mezzanine Card (PMC) module that conforms to the PMC standard for Jn1 and Jn2 but uses Jn3 and Jn4 to support a variety of telemunications interfaces. The PTMC site on the media gateway is configured similar to a PT3MC, a subset of the PTMC specification that supports UTOPIA, Ethernet Reduced Media-Independent Interface (RMII), and puter telephony bus interfaces on Jn3/4. An optional fifth connector (Jn5) is added to support the two MII interfaces supported by the MSC8101 device. Jn5 is a proprietary connector, effectively supporting an enhanced PTMC that is backward-patible with existing PTMCs.
