Name/Description
FSYNC
I
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.
CHICLK
I
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.
CKSPD0
I
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. If CHICLK is connected to a
16.384 MHz source, CKSPD0 should be tied to VDD33.
CKSPD1

MPUCLK
I Processor Clock. This clock is used to sample address, data, and control signals from the
microprocessor. This clock must be within the range of 0 MHz—66 MHz. Required for operation.
CS
I
Chip Select. Active-low chip select. This input is held low for the duration of any read or write access
to the device. Required for operation.
AS
I
Address Strobe. Active-low address strobe that is one MPUCLK cycle wide at the start of a
microprocessor access cycle to the device. This is used to initiate a microprocessor access. Required
for operation.

INT
Note: The device is little-endian; the least significant byte is stored in the lowest address and the
most significant byte is stored in the highest address. Care must be exercised when
connecting to microprocessors that use big-endian byte ordering.
I/O Data [15:0]. Data bus for all transfers between the microprocessor and the internal registers. The
balls are inputs during write cycles and outputs during read cycles. DATA[15] is the most significant
bit, and DATA[0] is the least significant bit. Required for operation.
I/O Control Port Parity [1:0]. Byte-wide parity bits for data. PAR[1] is the parity for DATA[15:8], and

3 Operating Conditions and Reliability
3.1 Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. 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.

3.3 Handling Precautions
Although electrostatic discharge (ESD) protection circuitry has been designed into this device, proper precautions must be
taken to avoid exposure to ESD and electrical overstress (EOS) during all handling, assembly, and test operations. 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.

3.4 Thermal Parameters (Definitions and Values)
System and circuit board level performance depends not only on device electrical characteristics, but also on device thermal
characteristics. 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

Note: Posted writes follow the same timing shown in Figure 5-17 on page 29 and Table 5-7 on page 29. A posted write may
return a DT prior to the device completing the write cycle. This allows the microprocessor to continue operation while
the device completes the write.

6 Register Description
This section describes the purpose and operation of each register bit, its dependencies, and its initial state.
6.1 Device Addressing Notes
All device addresses shown are physical byte offset addresses in the microprocessor space, not the actual addresses in the
device itself. 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.

6.6 Connection Store Generator Registers
The connection store is not initialized on powerup nor reset. Although it can be manually initialized by writing all locations
via the microprocessor interface, the CSG is provided to independently fill the connection store with known data. The user
can program the CSG to fill with a variety of patterns or with user-defined fixed data. Since the connection store is greater
than 16 bits wide, the CSG, in general, has pairs of registers associated with controlling the data to be loaded.

Table 6-48 on page 50) to provide this control. These registers provide the time-slot offset. The Transmit_CHI_Configuration
registers provide the bit and fractional bit offset control.

8 Connection Store
The connection store RAM contains the per-time-slot control information for outgoing time slots. 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
A[14:7]
16 MHz
TS (0—255)
8 MHz
TS x 2 (TS = 0—127)
4 MHz
TS x 4 (TS = 0—63)
2 MHz
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]).

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

8 Mbits/s
TS x 2 (TS = 0—127)

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.

* 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.
