The static parameters (drive currents, switching thresholds, etc.) for each ball type (input, output, etc.) are described in Table 4-1 on page 18 through Table 4-3. Table 2-5. Timing Port Ball Name Type FSYNC I Name/Description Frame Synchronization. This signal indicates the beginning of a 125 µs frame event (8 kHz). The FSYNC ball can be programmed as active-low or active-high, but its polarity is the same for all concentration highway interfaces (CHI). FSYNC can be sampled on either the positive or negative edge of CHICLK. Time-slot numbers and bit offsets for each CHI are assigned relative to the detection of FSYNC. Clock. This is the master synchronous clock for the transmit and receive concentration highways. The frequency can be 8.192 MHz or 16.384 MHz. It must be at least as fast as the highest CHI data rate. Clock Speed. Static control input that should be tied according to the frequency of CHICLK. If CHICLK is connected to an 8.192 MHz source, CKSPD0 should be tied to VSS.

These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability. Table 3-1.

Agere employs both a human-body model (HBM) and a charged-device model (CDM) qualification requirement in order to determine ESD-susceptibility limits and protection design evaluation. ESD voltage thresholds are dependent on the circuit parameters used in each of the models, as defined by JEDEC’s JESD22-A114 (HBM) and JESD22-C101 (CDM) standards. Table 3-3.

The thermal characteristics frequently determine the limits of circuit board or system performance, and they can be a major cost adder or cost avoidance factor. When the die temperature is kept below 125 °C, temperature-activated failure mechanisms are minimized. The thermal parameters that Agere provides for its packages help the chip and system designer choose the best package for their applications, including allowing the system designer to thermally design and integrate their systems. It should be noted that all the parameters listed below are affected, to varying degrees, by package design (including paddle size) and choice of materials, the amount of copper in the test board or system board, and system airflow. ΘJA - Junction to Air Thermal Resistance ΘJA is a number used to express the thermal performance of a part under JEDEC standard natural convection conditions. ΘJA is calculated using the following formula: ΘJA = (TJ – Tamb) / P; where P = power ΘJMA - Junction to Moving Air Thermal Resistance ΘJMA is effectively identical to ΘJA but represents performance of a part mounted on a JEDEC four layer board inside a wind tunnel with forced air convection. ΘJMA is reported at airflows of 200 LFPM and 500 LFPM (linear feet per minute), which roughly correspond to 1 m/s and 2.5 m/s (respectively). ΘJMA is calculated using the following formula: ΘJMA = (TJ – Tamb) / P ΘJC - Junction to Case Thermal Resistance ΘJC is the thermal resistance from junction to the top of the case. This number is determined by forcing nearly 100% of the heat generated in the die out the top of the package by lowering the top case temperature. This is done by placing the top of the package in contact with a copper slug kept at room temperature using a liquid refrigeration unit. ΘJC is calculated using the following formula: ΘJC = (TJ – TC) / P ΘJB - Junction to Board Thermal Resistance ΘJB is the thermal resistance from junction to board. This number is determined by forcing the heat generated in the die out of the package through the leads or balls by lowering the board temperature and insulating the package top. This is done using a special fixture, which keeps the board in contact with a water chilled copper slug around the perimeter of the package while insulating the package top. ΘJB is calculated using the following formula: ΘJB = (TJ – TB) / P ΨJT - Junction Temperature to Case Temperature ΨJT correlates the junction temperature to the case temperature. It is generally used by the customer to infer the junction temperature while the part is operating in their system. It is not considered a true thermal resistance. ΨJT is calculated using the following formula: ΨJT = (TJ – TC) / P Table 3-4.

The device uses 217 bytes of address spectrum. The following assumptions are made: The device is connected to the microprocessor as a 16-bit word accessed device (not byte addressable), with ADDR[00] connected to address bit 1 of the microprocessor. The microprocessor’s address bit 0 (high/low byte) is not used by the device. Note: All addresses are expressed in hexadecimal. Unless otherwise indicated by a 0x, register bit states (in default states) are expressed in binary. 6.2 Acronyms Used CS—Connection store. CSG—Connection store generator. PLL—Phase-locked loop. SF—Switch fabric. TPG—Test pattern generator. TPM—Test pattern monitor. VCO—Voltage-controlled oscillator. 6.3 Address Map Table 6-1.

Data_Store_Time_Slot_Capture_Select (Read/Write) TSI-2 2k x 2k Time-Slot Interchanger For diagnostic and other purposes, a single incoming time slot can be sampled and made available to be read from the microprocessor interface. This register specifies which time slot will be sampled. Address 0x01142 Bit 15:13 Unused. 12:0 Name/Description Default — Data_Store_Time_Slot_Capture. Specifies which time slot should be captured (sampled) 0x0000 (0—8,191). This value is a function of the stream (CHI) number, the data rate of the CHI, the time-slot offset of the CHI (RTO), and the desired time slot (TS) of the CHI. The following algorithms can be used to determine the value for this field: For a 16 Mbits/s CHI: — (32 x [(TS + RTO) mod 256]) + CHI, where TS and RTO range from 0—255.

Connection_Store_Parity_Error_Address_Trap (CORWN) Data Sheet, Revision 3 September 21, 2005 As the connection store is continually read, its parity is checked. If an error is detected, the location with the error is saved in this register and the Connection_Store_Parity_Error (see Table 7-1 on page 54) error bit is set. If in clear-on-read (COR) mode, when this register is read, the Connection_Store_Parity_Error bit is cleared.

Transmit_Link_Offset (Read/Write) This register displays/controls the offset of the transmit links with respect to the switch fabric. Normally, the Transmit_Link_Offset is determined by the CHI frame synchronization's relative position to the switch fabric synchronization. In this case, bit [15] of this register should be set to 0. Address 0x0114C Bit 15 Name/Description Force_Transmit_Link_Offset. 0 = Allows the switch fabric to self-determine its offsets. 1 = Forces the device to use the Transmit_Offset value to align the switch fabric to a deterministic position relative to the CHI frame synchronization. If this is set to 1, this register value should be set and the system allowed to stabilize (more than 250 µs) prior to reading the value in Receive_Link_Offset (see Table 7-6). Transmit_Offset. If Force_Transmit_Link_Offset is set to 1, this value will force the switch fabric to align itself this many time slots off from the CHI frame synchronization.

Each location in the RAM corresponds to one outgoing time slot and contains all the time-slot specific control information for that time slot. The specific address offset into the RAM is calculated as follows: ADDR[15] = 0. ADDR[14:7] destination (outgoing) time-slot number of stream identified by address bits [6:2]. ADDR[6:2] destination (outgoing) stream (CHI) number. ADDR[01] 0 = Low_Control, 1 = High_Control. ADDR[00] = 0 (no byte addressability). Address bits [14:7] are dependent on the destination (outgoing) CHI rate and should be calculated as follows, where TS is the outgoing CHI time-slot number: Rate 16 MHz 8 MHz 4 MHz 2 MHz A[14:7] TS (0—255) TS x 2 (TS = 0—127) TS x 4 (TS = 0—63) TS x 8 (TS = 0—31) Table 8-1. Low_Control_Word (Read/Write) The low-control word in the connection store has two functions. Normally, it is used to program the address of the incoming time slot to which the outgoing time slot is connected. The outgoing time slot is implied by the connection store address as described above. This normal switch operation will apply if the time-slot mode bits in the high-control word are set to low latency or frame integrity switching modes. If alternate data mode is selected, the low control word contains the alternate data (see Table 8-2, bit [9:8]). Address 0x10000— 0x17FFC Bit* 15:8 Name/Description Default Alternate_Data_Pattern_2. If alternate data is selected by the mode bits in the corre— sponding high control location, the data in this byte will alternate with the Alternate_Data_Pattern_1 pattern and be sent out on the transmit time slot. — Time_Slot_Pointer. This field selects the desired time slot from the source stream (CHI). This value is dependent on the speed (data rate) of the receive CHI specified by Stream_Pointer and should be programmed as follows, where TS is the desired time-slot number: Receive CHI Rate Time_Slot_Pointer [7:0] 16 Mbits/s TS (0—255) 8 Mbits/s TS x 2 (TS = 0—127) 4 Mbits/s TS x 4 (TS = 0—63) 2 Mbits/s TS x 8 (TS = 0—31) Alternate_Data_Pattern_1. If alternate data is selected by the mode bits in the corre— sponding high control location, the data in this byte will alternate with the Alternate_Data_Pattern_2 pattern and be sent out on the transmit time slot. Stream_Pointer. This field selects one of 32 incoming streams. — 12:5 7:0 4:0 * Bits [15:0] have dual meaning based on the value in the Time_Slot_Mode field of the High_Control_Word (see Table 8-2). If the Time_Slot_Mode field is set to 10 (alternate data), then bits [15:0] have the following meaning: Bits [7:0] are set to Alternate_Data_Pattern_1. Bits [15:8] are set to Alternate_Data_Pattern_2. If the Time_Slot_Mode field is set to anything other than 10, then bits [15:0] have the following meaning: Bits [4:0] are set to Stream_Pointer. Bits [12:5] are set to Time_Slot_Pointer. Bits [15:13] are reserved. 58 Agere Systems Inc. Data Sheet, Revision 3 September 21, 2005 Table 8-2.
