PM4351-NI

The PM4351-NI is one member of the PM4351 family which is designed as the combined E1/T1 transceiver device that can be used in wide range of applications such as (1)T1/E1 Wireless Digital Loop Carriers (DLC's) and Cellular Base Stations; (2)T1/E1 Internet Access Equipment; (3)T1/E1 Channel Service Units (CSU); (4)T1/E1 Frame Relay Interfaces; (5)T1/E1 ATM Interfaces; (6)T1/E1 Multiplexers (CPE MUX); (7)Digital Private Branch Exchanges (PBX); (8)Digital Access Cross-Connect Systems (DACS) and Electronic DSX Cross-Connect Systems (EDSX); (9)ISDN Primary Rate Interfaces (PRI); (10)Test Equipment.

Features of the PM4351-NI are:(1)Software selectable between T1/J1 and E1 operation on a per-device basis;(2)Provides encoding and decoding of B8ZS, HDB3 and AMI line codes;(3)Provides receive equalization, clock recovery and line performance monitoring;(4)Provides transmit and receive jitter attenuation;(5)Provides digitally programmable long haul and short haul line build out;(6)Provides four full-featured HDLC controllers, each with 128-byte transmit and receive FIFO buffers.etc.

The absolute maximum ratings of the PM4351-NI can be summarized as:(1)Ambient Temperature under Bias: -55°C to +125°C;(2)Storage Temperature: -65°C to +150°C;(3)Supply Voltage: -0.3 V to + 3.5 V;(4)Voltage on Any Pin: -0.3 to BIAS + 0.3V;(5)Static Discharge Voltage: ±1000 V;(6)Latch-Up Current: ±100 mA;(7)DC Input Current: ±20 mA;(8)Lead Temperature: +230 °C; (9)Maximum Junction Temperature: +150 °C.
