5 / 160 page  Preliminary Information MT9076 5 42 17 RxMF/ TxFP Receive Multiframe Boundary / Transmit Frame Boundary (5V tolerant Output). If the control bit Tx8KEN (page 02H address 10H bit 2) is low, this negative output pulse delimits the received multiframe boundary. The next frame output on the data stream (DSTo) is basic frame zero on the T1 or PCM 30 link. In E1 mode this receive multiframe signal can be related to either the receive CRC multiframe (page 01H, address 17H, bit 6, MFSEL=1) or the receive signaling multiframe (MFSEL=0). If the control bit Tx8KEN is set high, this positive output pulse delimits the frame boundary (the first bit transmit in the frame) for the digital output stream on pins TXA and TXB. 43 18 BS/LS Bus/Line Syncronization Mode Selection (5V tolerant Input). If high, C4b and F0b will be inputs; if low, C4b and F0b will be outputs. 44 22 Exclk 2.048 MHz in E1 mode or 1.544MHz in T1 mode, Extracted Clock (5V tolerant Output). The clock extracted from the received signal and used internally to clock in data received on RTIP and RRING. 45 23 C4b 4.096 MHz System Clock (5V tolerant Input/Output). C4b is the clock for the ST-BUS sections and transmit serial PCM data of the MT9076. In the free-run (S/FR/Exclki=0) or line synchronous mode (S/FR/Exclki=1 and BS/LS=0) this signal is an output, while in bus synchronous mode (S/FR/Exclki=1 and BS/LS=1) this signal is an input clock. 46 24 F0b Frame Pulse (5V tolerant Input/Output). This is the ST-BUS frame synchronization signal, which delimits the 32 channel frame of CSTi, CSTo, DSTi, DSTo and the PCM30 link. In the free-run (S/FR/Exclki=0) or line synchronous mode (S/FR/Exclki=1 and BS/LS=0) this signal is an output, while in bus synchronous mode (S/FR/Exclki=1 and BS/LS=1) this signal is an input. 47 25 RxFP Receive Frame Pulse/Receive CCS Clock (5V tolerant Output). An 8kHz pulse signal, which is low for one extracted clock period. This signal is synchronized to the receive DS1 or PCM 30 basic frame boundary. 48 26 IC1 Internal Connection. Must be left open for normal operation. 49 27 VSS2 Negative Power Supply. Digital ground. 50 28 VDD2 Positive Power Supply. Digital supply (+3.3V ± 5%). 51 29 VDDATx Transmit Analog Power Supply. Analog supply for the LIU transmitter (+3.3V ±5%). 52 53 30 31 TTIP TRING Transmit TIP and RING(Output). Differential outputs for the transmit line signal - must be transformer coupled (See Figure 6). 54 32 GNDATx Transmit Analog Ground . Analog ground for the LIU transmitter. 55 33 Tdi IEEE 1149.1a Test Data Input (3V Input). If not used, this pin should be pulled high. 56 34 Tdo IEEE 1149.1a Test Data Output (5V tolerant Output). If not used, this pin should be left unconnected. 57 35 Tms IEEE 1149.1a Test Mode Selection (3V Input). If not used, this pin should be pulled high. 58 36 Tclk IEEE 1149.1a Test Clock Signal (3V Input). If not used, this pin should be pulled high. 59 37 Trst IEEE 1149.1a Reset Signal (3V Input). If not used, this pin should be held low. 60 38 TxAO Transmit All Ones (Input). High - TTIP, TRING will transmit data normally. Low - TTIP, TRING will transmit an all ones signal.
