It is used as the reference clock by both clock recovery and clock synthesis circuits. When the WAN Synchronization controller is used, REFCLK is supplied using a VCXO. In this application, the transmit direction can be looped timed to any of the line receivers in order to meet wander transfer and holdover requirements. . RXD+ RXD- SD Differential AA1 PECL Y2 inputs SingleEnded PECL Input W3 The receive differential data inputs (RXD+, RXD-) contain the NRZ bit serial receive stream. The receive clock is recovered from the RXD+/- bit stream. Please refer to the Operation section for a discussion of PECL interfacing issues. The Signal Detect pin (SD) indicates the presence of valid receive signal power from the Optical Physical Medium Dependent Device. A PECL high indicates the presence of valid data and a PECL low indicates a loss of signal. It is mandatory that SD be terminated into the equivalent network that RXD+/- is terminated into. . RCLK Output AB14 The receive byte clock (RCLK) provides a timing reference for the S/UNI-STAR receive outputs. RCLK is a divide by eight of the recovered line rate clock (19.44 MHz). .

RFPO pulses high for one RCLK cycle every 2430 RCLK cycles (STS-3c (STM-1)). RFPO is updated on the rising edge of RCLK. RALRM Output AB15 The Receive Alarm (RALRM) output indicates the state of the receive framing. RALRM is low if no receive alarms are active. RALRM is high if line AIS (LAIS), path AIS (PAIS), line RDI (LRDI), path RDI (PRDI), enhanced path RDI (PERDI), loss of signal (LOS), loss of frame (LOF), out of frame (OOF), loss of pointer (LOP), loss of cell delineation (LCD), signal fail BER (SFBER), signal degrade BER (SDBER), path trace identification mismatch (TIM), path signal label mismatch (PSLM) is detected in the channel. Each alarm can be individually enabled using bits in the S/UNI-STAR Channel Alarm Control registers #1 and #2. RALRM is updated on the rising edge of RCLK. . TXD+ TXD- Differential W2 TTL output Y1 (externally converted to PECL) TXC+ TXC- Differential U4 TTL output V3 (externally converted to PECL) The transmit differential data outputs (TXD+, TXD-) contain the 155.52 Mbit/s transmit stream. .

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 12 PM5352 S/UNI STAR DATA SHEET PMC-1990421 ISSUE 2 Pin Name Type TFPI Input Pin No. Y7 SATURN USER NETWORK INTERFACE 155 (STAR) Function The active high framing position (TFPI) signal is an 8 kHz timing marker for the transmitter. TFPI is used to align the SONET/SDH transport frame generated by the S/UNI-STAR device to a system reference. TFPI is internally used to align a master frame pulse counter. When TFPI is not used, this counter is free-running. TFPI should be brought high for a single TCLK period every 2430 (STS-3c (STM-1)) TCLK cycles, or a multiple thereof. TFPI shall be tied low if such synchronization is not required. TFPI cannot be used as an input to a loop-timed channel. For TFPI to operate correctly it is required that the TCLK/TFPO output be configured to output the CSU byte clock. The TFPI_EN register bits allow use of the global framing pulse counter and TFPI for framing alignment. TFPI is sampled on the rising edge of TCLK, but only when the TTSEL register bit is set to logic zero. When TTSEL is set to logic one, TFPI is unused. TFPO Output AB11 The Transmit Frame Pulse Output (TFPO) pulses high for one TCLK cycle every 2430 TCLK cycles and provides an 8 KHz timing reference. TFPO can be enabled using TFPO_CH[1:0] configuration register bits, with the restriction that the device must be self-timed (not in loop-timed or line-loopback modes). TFPO is updated on the rising edge of TCLK. TCLK Output AC11 The transmit byte clock (TCLK) output provides a timing reference for the S/UNI-STAR self-timed channel. TCLK always provide a divide by eight of the synthesized line rate clock and thus has a nominal frequency of 19.44 MHz. TFPI is sampled on the rising edge of TCLK. TCLK does not apply to internally loop-timed channels, in which case RCLK provides transmit timing information.

(ATM) The transmit parity (TPRTY) signal indicates the parity of the TDAT[15:0] bus. A parity error is indicated by a status bit and a maskable interrupt. Cells with parity errors are inserted in the transmit stream, so the TPRTY input may be unused. Odd or even parity selection is made using the RXPTYP register bit.

(POS) TSOP indicates the first word of a packet. TSOP is required to be present at the beginning of every packet for proper operation. TSOP is considered valid only when TENB is simultaneously asserted and the S/UNI-STAR is selected via TADR[2:0]. TSOP is sampled on the rising edge of TFCLK. TENB Input (ATM) J22 UTOPIA Transmit Multi-PHY Write Enable (TENB) signal. The TENB signal is an active low input which is used along with the TADR[2:0] inputs to initiate writes to the transmit FIFO’s. TENB works as follows. When sampled high, no write is performed, but the TADR[2:0] address is latched to identify the transmit FIFO to be accessed. When TENB is sampled low, the word on the TDAT bus is written into the transmit FIFO that is selected by the TADR[2:0} address bus. A complete 53 octet cell must be written to the transmit FIFO before it is inserted into the transmit stream. Idle cells are inserted when a complete cell is not available.

(POS) The S/UNI-STAR supports both byte-level and packet-level transfer. Packet-level transfer operates in a similar fashion to Utopia, with a selection phase when TENB is deasserted and a transfer phase when TENB is asserted. While TENB is asserted, TADR[2:0] is used for polling PTPA and the currently selected PHY status is provided on STPA. Byte level transfer works on a cycle basis. When TENB is asserted, data is transferred to the selected PHY. Nothing happens when TENB is deasserted. Polling is not available and packet availability is indicated by DTPA.

It is mandatory that every ground pin (VSS) be connected to the printed circuit board ground plane to ensure a reliable device operation. 4. It is mandatory that every power pin (VDD) be connected to the printed circuit board power plane to ensure a reliable device operation. 5. All analog power and ground can be sensitive to noise. They must be isolated from the digital power and ground. Care must be taken to decouple these pins from each other and all other analog power and ground pins. 6. Due to ESD protection structures in the pads it is necessary to exercise caution when powering a device up or down. ESD protection devices behave as diodes between power supply pins and from I/O pins to power supply pins. Under extreme conditions it is possible to blow these ESD protection devices or trigger latch up. Please adhere to the recommended power supply sequencing as described in the OPERATION section of PM5351 S/UNI-TETRA datasheet. 7. Some device pins can be made 5V tolerant by connecting the BIAS pins to a 5V power supply, while some other pins are 3.3V only. In summary, the system interface (ATM or POS) is 3.3V only while the microprocessor interface, SONET and line interfaces are 5V tolerant. 3.3V only I/O’s: RDAT[15:0], RSOC/RSOP, RPRTY, RENB, REOP, RMOD, RERR, RVAL, TDAT[15:0], TSOC/TSOP, TPRTY, TENB, TEOP, TMOD, TERR, RCA/RPA, DRCA/DRPA, TCA/PTPA, STPA, DTCA/DTPA, RADR[3:0], TADR[3:0], PHY_OEN 5V tolerant I/O’s: REFCLK, RCLK, RFPO, RALRM, TCLK, TFPO, TFPI, RSD, RSDCLK, TSD, TSDCLK.

This test feature may be used for board testing. Test mode registers are used to apply test vectors during production testing of the S/UNI-STAR. Test mode registers (as opposed to normal mode registers) are selected when TRS (A[10]) is high. Test mode registers may also be used for board testing. When all of the TSBs within the S/UNI-STAR are placed in test mode 0, device inputs may be read and device outputs may be forced via the microprocessor interface (refer to the section "Test Mode 0" for details). In addition, the S/UNI-STAR also supports a standard IEEE 1149.1 fivesignal JTAG boundary scan test port for use in board testing. All digital device inputs may be read and all digital device outputs may be forced via the JTAG test port.

Writing values into unused register bits has no effect. However, to ensure software compatibility with future, feature-enhanced versions of the product, unused register bits must be written with logic zero. Reading back unused bits can produce either a logic one or a logic zero; hence, unused register bits should be masked off by software when read. 2. Writable test mode register bits are not initialized upon reset unless otherwise noted.

All bits, except PMCTST, PMCATST and BYPASS are reset to zero by a reset of the S/UNI-STAR using either the RSTB input or the Master Reset register. PMCTST and BYPASS are reset when CSB is logic one. PMCATST is reset when both CSB is high and RSTB is low. PMCTST, PMCATST and BYPASS can also be reset by writing a logic zero to the corresponding register bit. HIZIO, HIZDATA: The HIZIO and HIZDATA bits control the tri-state modes of the S/UNI-STAR . While the HIZIO bit is a logic one, all output pins of the S/UNI-STAR except the data bus and output TDO are held tri-state. The microprocessor interface is still active. While the HIZDATA bit is a logic one, the data bus is also held in a high-impedance state which inhibits microprocessor read cycles. The HIZDATA bit is overridden by the DBCTRL bit. IOTST: The IOTST bit is used to allow normal microprocessor access to the test registers and control the test mode in each TSB block in the S/UNI-STAR for board level testing. When IOTST is a logic one, all blocks are held in test mode and the microprocessor may write to a block's test mode 0 registers to manipulate the outputs of the block and consequentially the device outputs (refer to the "Test Mode 0 Details" in the "Test Features" section). PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 58 PM5352 S/UNI STAR DATA SHEET PMC-1990421 ISSUE 2 SATURN USER NETWORK INTERFACE 155 (STAR) DBCTRL: The DBCTRL bit is used to pass control of the data bus drivers to the CSB pin. When the DBCTRL bit is set to logic one and either IOTST or PMCTST are logic one, the CSB pin controls the output enable for the data bus. While the DBCTRL bit is set, holding the CSB pin high causes the S/UNI-STAR to drive the data bus and holding the CSB pin low tri-states the data bus. The DBCTRL bit overrides the HIZDATA bit. The DBCTRL bit is used to measure the drive capability of the data bus driver pads. PMCTST: The PMCTST bit is used to configure the S/UNI-STAR for PMC's manufacturing tests. When PMCTST is set to logic one, the S/UNI-STAR microprocessor port becomes the test access port used to run the PMC "canned" manufacturing test vectors. The PMCTST bit is logically "ORed" with the IOTST bit, and can be cleared by setting CSB to logic one or by writing logic zero to the bit. PMCATST: The PMCATST bit is used to configure the analog portion of the S/UNI-STAR for PMC's manufacturing tests. Reserved: The reserved bit must be programmed to logic one for proper operation. 9.2 JTAG Test Port The S/UNI-STAR JTAG Test Access Port (TAP) allows access to the TAP controller and the 4 TAP registers: instruction, bypass, device identification and boundary scan. Using the TAP, device input logic levels can be read, device outputs can be forced, the device can be identified and the device scan path can be bypassed. For more details on the JTAG port, please refer to the Operations section.
