Features
* * * * * * * Pin-for-Pin replacement for industry-standard PEB2095 part Up to 2.0km line interface performance NT (LT) and TE mode support IOM1 and IOM2 backplane interface modes Special function pins for interface to other INT2095's or layer-2 devices Custom versions with Intronic core technology Low Power dynamic operation Single 5V supply 28-pin PLCC (standard) package
Description
The Intronic Semiconductor INT2095 is a fully featured replacement for the industry standard Up interface layer-1 device. It supports loop lengths up to 2.0km over AWG24 cable and provides all signal conditioning, equalization and adaptive threshold adjustment to optimize line performance. The backplane interface supports both IOM1 and IOM2 modes and provides access to all subchannels of the interface including B, D, CI and M-channels. Special function pins (X0-X4) and a master clock output are included in the device for integration with other INT2095's or layer-2 devices.

Description of Terms
ENCKB: Enable clocks in TE mode, deactivated state. Active-low input signal. When high, the clock outputs are in the high impedance state. PFOFF: NT mode Powerfeed off state. Also indicated by a HI on the C/I channel. MPF: Main Power Feed serial input, 8-bits synchronous with the B1 channel of the IOM interface. CONF4: General purpose output which is programmed via the Monitor channel registers. TS2-TS0: IOM Timeslot assignment number (0 to 7) in NT mode.
