Table 6
Although the EMDP can only transport data at either of these two instantaneous rates, it can
support any average data rate between them by adjusting the ratio of frames with stuffing to those
without stuffing. When alternate frame stuffing is used the EMDP will transport data at the
nominal rate shown in
or a gapped clock produced by combining RDATA_ST and BIT_CLK can be used to create a
continuous (i.e., not gapped) clock whose frequency is at the average receive data rate. The PLL
characteristics depend on the jitter and wander requirements for the output clock.
EDSP Registers
EDSP provides access to various internal registers via microprocessor interface. Ten write registers
and seven read registers are available in the EDSP. Several new registers are added in comparison
to previous MDSP chips enabling a more programmable and powerful EDSP.
