1. FEATURES
1.1 General
1.2 Line Interface
1.3 Jitter Attenuator (T1/E1 Modes Only)
§ 64-pin, 10mm x 10mm LQFP package
§ 3.3V supply with 5V-tolerant inputs and outputs
§ Evaluation kits
§ IEEE 1149.1 JTAG Boundary Scan
§ Driver source code available from the factory
§ Requires a single master clock (MCLK) for E1, T1, or J1 operation. Master clock can be
§ Fully software configurable
§ Short- and long-haul applications
§ Automatic receive sensitivity adjustments
§ Ranges include 0dB to -43dB or 0dB to -12dB for E1 applications; 0dB to -36dB or 0dB to -15dB
§ Receive level indication in 2.5dB steps from -42.5dB to -2.5dB
§ Internal receive termination option for 75Ω, 100Ω, 110Ω, and 120Ω lines
§ Monitor application gain settings of 20dB, 26dB, and 32dB
§ G.703 receive-synchronization signal mode
§ Flexible transmit-waveform generation
§ T1 DSX-1 line build-outs
§ E1 waveforms include G.703 waveshapes for both 75Ω coax and 120Ω twisted cables
§ AIS generation independent of loopbacks
§ Alternating ones and zeros generation
§ Square-wave output
§ Open-drain output option
§ Transmitter power-down
§ Transmitter 50mA short-circuit limiter with exceeded indication of current limit
§ Transmit open-circuit-detected indication
§ 32-bit or 128-bit crystal-less jitter attenuator
§ Requires only a 2.048MHz master clock for both E1 and T1 operation with the option to use
§ Can be placed in either the receive or transmit path or disabled
§ Limit trip indication
2.048MHz, 4.096MHz, 8.192MHz, or 16.384MHz. Option to use 1.544MHz, 3.088MHz,
