5. DETAILED FEATURES
5.1 Global Features
5.2 Receiver
5.3 Transmitter
5.4 Jitter Attenuator
Three interface modes: hardware, 8-/16-bit parallel bus, and SPI serial bus
Independent per-port operation (e.g., line rate, jitter attenuator placement, or loopback type)
Clock, data, and control signals can be inverted to allow a glueless interface to other devices
Manual or automatic one-second update of performance monitoring counters
Each port can be put into a low-power standby mode when not being used
Requires only a single reference clock for all three LIU data rates using internal clock rate adapter
Jitter attenuators can be used in either transmit or receive path
Detection of loss-of-transmit clock
Two programmable I/O pins per port
Optional global write mode configures all LIUs at the same time
Glueless interface to neighboring framer and mapper components
AGC/equalizer block handles from 0 to 22dB of cable loss
Programmable internal termination resistor
Loss-of-lock (LOL) PLL status indication
Interfaces directly to a DSX monitor signal (~20dB flat loss) using built-in preamp
Digital and analog loss-of-signal (LOS) detectors (compliant with ANSI T1.231 and ITU G.775)
Software programmable B3ZS/HDB3 or AMI decoding
Detection and accumulation of bipolar violations (BPV), code violations (CV), and
excessive zeros occurrences (EXZ)
Detection of receipt of B3ZS/HDB3 codewords
Binary or bipolar framer interface
On-board programmable PRBS detector
Per-channel power-down control
Standards-compliant waveshaping
Programmable waveshaping
Programmable internal termination resistor
Binary or bipolar framer interface
Gapped clock capable up to 78MHz with jitter attenuator in transmit path
Wide 50 ±20% transmit clock duty cycle
Transmit common clock option
Software programmable B3ZS/HDB3 or AMI decoding
Programmable insertion of bipolar violations (BPV), code violations (CV), and excessive zeros (EXZ)
AIS generator: unframed all ones, framed DS3 AIS, and STS-1 AIS-L
Line build-out (LBO) control
High-impedance line-driver output mode to support protection-switching applications
Per-channel power-down control
Output driver monitor
One jitter attenuator per port
Fully integrated, requires no external components
Meets all applicable ANSI, ITU, ETSI, and Telcordia jitter transfer and output jitter requirements
Can be placed in the transmit path, receive path or disabled
Programmable FIFO depth: 16, 32, 64, or 128 bits
Overflow and underflow status indications
