BT8370KPF

The BT8370KPF is single chip transceiver for T1/E1 and Integrated Service Digital Network (ISDN) primary rate interfaces, operating at 1.544 Mbps or 2.048 Mbps. The devices combine a sophisticated framer, transmit and receive slip buffers, and an on-chip physical line interface to provide a complete T1/E1 transceiver.

The features of BT8370KPF can be summarized as:(1)Single-chip T1/E1 framer with short/long-haul physical line interface; (2)Frames to popular T1/E1 standards:T1: SF, ESF, SLC 96, T1DM;E1: PCM-30, G.704, G.706, G.732 ISDN primary rate; (3)On-chip physical line interface compatible with: DSX-1/E1 short-haul signals, DS-1 (T1.403) and ETSI long-haul signals; (4)Two-frame transmit and receive PCM slip buffers; (5)Clock rate adapter synthesizes jitter attenuated system clocks from an internal or external reference; (6)Parallel 8-bit microprocessor port supports Intel or Motorola buses ; (7)Automated Facility Data Link (FDL) management; (8)BERT generation and counting; (9)Two full-duplex HDLC controllers for data link and LAPD/SS7 signaling; (10)B8ZS/HDB3/Bit 7 zero suppression; (11)80-pin MQFP surface-mount package ; (12)Operates from a single +5 Vdc ±5% power supply; (13)Low-power CMOS technology.

The absolute maximum ratings of BT8370KPF are:(1)Power Supply (measured to GND):0.5V to 7 V; (2)Voltage Differential (between any 2 VDD pins):0.5 V; (3)Constant Voltage on any Signal Pin:1.0V to VDD + 0.5 V; (4)Constant Current on any Signal Pin:10mA to +10 mA; (5)Transient Current on any Signal Pin:-350mA to +400mA; (6)Storage Temperature:65°C to 150 °C; (7)Junction Temperature:(jA x VDD x IDD)+Tamb :-40°C to 125 °C; (8)Vapor Phase Soldering Temperature (1 minute):220 °C; (9)Thermal Resistance (80MQFP), Still Air:43 °C/W; (10)Transient Voltage on any Signal Pin:HBM rating ±2kV,CDM rating±700kV, MMM rating±200kV.
