10.0 ELASTIC STORE OPERATION
The DS2143 has an onboard two-frame (512 bits) elastic store. This elastic store can be enabled via
RCR2.1. If the elastic store is enabled (RCR2.1=1), then the user must provide either a 1.544 MHz
(RCR2.2=0) or 2.048 MHz (RCR2.2=1) clock at the SYSCLK pin. If the elastic store is enabled, then the
user has the option of either providing a frame sync at the RFSYNC pin (RCR1.5=1) or having the
RFSYNC pin provide a pulse on frame or multiframe boundaries (RCR1.5=0). If the user wishes to
obtain pulses at the frame boundary, then RCR1.6 must be set to 0, and if the user wishes to have pulses
occur at the multiframe boundary, then RCR1.6 must be set to 1. If the user selects to apply a 1.544 MHz
clock to the SYSCLK pin, then every fourth channel will be deleted and the F-bit position inserted
(forced to 1). Hence channels 1, 5, 9, 13, 17, 21, 25, and 29 (timeslots 0, 4, 8, 12, 16, 20, 24, and 28) will
be deleted. Also, in 1.544 MHz applications, the RCHBLK output will not be active in channels 25
through 32 (or in other words, RCBR4 is not active). See Section 13 for more details. If the 512-bit
elastic buffer either fills or empties, a controlled slip will occur. If the buffer empties, then a full frame of
data (256 bits) will be repeated at RSER and the SR1.4 and RIR.3 bits will be set to a 1. If the buffer fills,
then a full frame of data will be deleted and the SR1.4 and RIR.4 bits will be set to a 1.
