• Recovers clock and data.
• Frames to and descrambles recovered
stream.
• Filters and captures Automatic
Protection Switch (APS) byes (K1, K2)
and detects APS byte failure.
• Detects signal degrade and signal
failure threshold crossing alarms.
• Captures and debounces
synchronization status byte (S1).
• Synthesizes the 155.52 MHz transmit
clock from a 19.44 MHz reference.
• Provides a single transmit frame pulse
input to align the transport frames to a
system reference.
• Provides single transmit clock as
timing reference for transmit outputs.
• Inserts register programmable APS
(K1 and K2) and synchronization
status (S1) bytes.
• Inserts PAIS, PRDI, LAIS, and LRDI.
• Scrambles the transmit data stream.
• Implements the ATM Forum User
Network Interface Specification.
• Inserts and extracts ATM cells into and
from the SONET SPE.
• Performs cell payload scrambling and
descrambling.
• Provides a UTOPIA Level 2-compliant
system interface.
• Provides synchronous 4-cell transmit
and receive FIFO buffers.

• Quad-channel ATM OC-3c
(155 Mb/s) PHY.
• Provides on-chip clock and data
recovery and clock synthesis.
• Exceeds Bellcore-GR-253 jitter
requirements.
• Provides a generic 8-bit
microprocessor interface for device
control and register access.
• Provides standard IEEE 1149.1 JTAG
test port for boundary scan.
• Counts received section BIP-8 (B1),
line BIP-24 (B2), and BIP-8 (B3)
errors, and line and path FEBEs.
• Detects LOS, OOF, LOF, LAIS, LRDI,
LOP, PAIS, PRDI, and PERDI.
• Provides individual divide by eight
recovered clocks for each channel.
• Provides individual 8 kHz receive
frame pulses for each channel.
