Quad Cell Delineation Block Device
PM7339 S/UNI®-CDB
• Provides a four cell FIFO for rate
decoupling between the line and a

latency may be reduced by changing
the number of operational cell FIFOs.
• Provides an 8 kHz reference input for
locking the transmit PLCP frame rate
to an externally applied frame
reference.
• Provides programmable pseudo-
random test sequence generation (up
to 232-1 bit length sequences
conforming to ITU-T O.151 standards).
Diagnostic abilities include single bit
error insertion or error insertion at bit
error rates ranging from 10-1 to 10-7.
LOOPBACK FEATURES
• Provides for diagnostic loopbacks and
line loopbacks.
GENERAL
• Provides an 8-bit microprocessor
interface for configuration, control and
status monitoring.
• Provides a standard five signal
P1149.1 JTAG test port for boundary
scan board test purposes.
