The TAMC020-TM is a standard Mid-Size/Full-Size MTCA.4 compliant Micro Rear Transition Module for TEWS TAMC261.
It distributes all P14 I/O lines of a PMC residing on the TAMC261 from the zone 3 interface connectors to a PIM module slot.
Additional lines are connected to the M-LVDS control and data lines of a TAMC261-2xR. These are distributed to normally unused pins of the J10 PIM slot connector so that a special PIM can be used to connect the M-LVDS control and data lines to the PMC back I/O signals.
According to MTCA.4, the TAMC020-TM provides an I2C EEPROM, an I2C temperature sensor and an I2C I/O Extender device. The I/O Extender is used to provide various management signals on the µRTM, with the management being handled by the MMC of the TAMC261.
