11 / 465 page xr XRT94L33 3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET Rev.1.2.0. 11 PIN # SIGNAL NAME I/O SIGNAL TYPE DESCRIPTION P2 REFCLK_N I LVPECL Transmit Reference Clock – Negative Polarity PECL Input: This input pin, along with “REFCLK_P” and “REFTTL” can be configured to function as the timing source for the STS-3/STM-1 Transmit Interface Block. If the user configures these two input pins to function as the timing source, then the user must apply a 155.52MHz clock signal, in the form of a PECL signal to these input pins. The user can configure these two inputs to function as the timing source by writing the appropriate data into the “Transmit Line Interface Control Register “ (Address Location = 0x0383) Note: Users should set this pin to “0” if “REFTTL” clock input is used P5 TXLDATO_P O LVPECL Transmit STS-3/STM-1 Data - Positive Polarity PECL Output: This output pin, along with TXLDATO_N functions as the Transmit Data Output, to the Optical Transceiver or to the system back-plane. For “High-Speed” Back-Plane Applications, the user should note that data is output from these output pins upon the rising/falling edge of “TXLCLKO_P/TXLCLKO_N”. Note: For APS (Automatic Protection Switching) purposes, this output pin, along with “TXLDATO_N” functions as the “Primary” Transmit STS-3/STM-1 Data Output Port. P6 TXLDATO_N O LVPECL Transmit STS-3/STM-1 Data – Negative Polarity PECL Output: This output pin, along with TXLDATO_P functions as the Transmit Data Output, to the Optical Transceiver or to the system back-plane. For “High-Speed” Back-Plane Applications, the user should note that data is output from these output pins upon the rising/falling edge of TXLCLKO_P/TXLCLKO_N. Note: For APS (Automatic Protection Switching) purposes, this output pin, along with “TXLDATO_P” functions as the “Primary” Transmit STS-3/STM-1 Data Output Port. M4 TXLDATO_R_P O LVPECL Transmit STS-3/STM-1 Data - Positive Polarity PECL Output - Redundant Port: This output pin, along with TXLDATO_R_N functions as the Transmit Data Output, to the Optical Transceiver or to the system back-plane. For “High-Speed” Back-Plane Applications, the user should note that data is output from these output pins upon the rising/falling edge of “TXLCLKO_R_P/TXLCLKO_R_N”). Note: For APS (Automatic Protection Switching) purposes, this output pin, along with “TXLDATO_N” functions as the “Redundant” Transmit STS-3/STM-4 Data Output Port. |
