The Bt8370/8375/8376 is a family of single chip transceivers for T1/E1 and Integrated Service Digital Network (ISDN) primary rate interfaces, operating at 1.544 Mbps or 2.048 Mbps. These 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 fully featured Bt8370 and short-haul Bt8375 and Bt8376 devices provide a programmable clock rate adapter for simplifying system bus interfacing. The adapter synthesizes standard clock signals from the receive or transmit line rate clocks or from an external reference.
1. Two-frame transmit and receive PCM slip buffers 2. Clock rate adapter synthesizes jitter attenuated system clocks from an internal or external reference 3. Parallel 8-bit microprocessor port supports Intel or Motorola buses 4. Automated Facility Data Link (FDL) management

The MAX3222 / MAX3232 / MAX3237 / MAX3241 transceivers have a proprietary low-dropout transmitter out put stage enabling true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. The devices require only four small 0.1µF external charge pump capacitors. The MAX3222, MAX3232, and MAX3241 are guaranteed to run at data rates of 120kbps while maintaining RS-232 output levels. The MAX3237 is guaranteed to run at data rates of 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode, while maintaining RS-232 output levels.
