Device Overview
The device uses the ST-BUS input frame pulse and the ST-BUS input clock to define the input frame boundary and
timing for the ST-BUS input streams with various data rates (2.048 Mb/s, 4.096 Mb/s and/or 8.192 Mb/s). The
output frame boundary is defined by the output frame pulses and the output clock timing for the ST-BUS output
streams with various data rates (2.048 Mb/s, 4.096 Mb/s and/or 8.192 Mb/s).
By using Zarlink’s message mode capability, microprocessor data can be broadcast to the data output streams on a
per channel basis. This feature is useful for transferring control and status information for external circuits or other
ST-BUS devices.
A non-multiplexed microprocessor port allows users to program the device with various operating modes and
switching configurations. Users can use the microprocessor port to perform register read/write, connection memory
read/write and data memory read operations. The microprocessor port has a 12-bit address bus, a 16-bit data bus
and four control signals.
The device also supports the mandatory requirements of the IEEE-1149.1 (JTAG) standard via the test port.

Functional Description
A functional block diagram of the ZL50012 is shown in Figure 1 on page 1.
2.1
ST-BUS Input Data Rate and Input Timing
The device has sixteen ST-BUS serial data inputs. Any of the sixteen inputs can be programmed to accept different
data rates, 2.048 Mb/s, 4.096 Mb/s or 8.192 Mb/s.
2.1.1
ST-BUS Input Operation Mode
Any ST-BUS input can be programmed to accept the 2.048 Mb/s, 4.096 Mb/s or 8.192 Mb/s data using Bit 0 to 2 in
the stream input control registers, SICR0 to SICR15 as shown in Table 20 on page 41 and Table 21 on page 43.
The maximum number of input channels is 512 channels. External pull-up or pull-down resistors are required for
any unused ST-BUS inputs.
2.1.2
Frame Pulse Input and Clock Input timing
The frame pulse input FPi accepts the frame pulse used for the highest input data rate. The frame pulse is an
8 kHz input signal which stays low for 244 ns, 122 ns or 61 ns for the input data rate of 2.048 Mb/s, 4.096 Mb/s or
8.192 Mb/s respectively. The frequency of CKi must be twice the highest data rate. For example, if users present
the ZL50012 with 2.048 Mb/s and 8.192 Mb/s input data, the device should be programmed to accept the input
clock of 16.384 MHz and the frame pulse which stays low for 61 ns.
Users have to program the CKIN2 - 0 bits in the Control Register (CR), for the width of the frame pulse low cycle
and the frequency of the input clock. See Table 1 for the programming of the CKIN0, CKIN1 and CKIN2 bits in the
Control Register.

The device also accepts positive or negative input frame pulse and ST-BUS input clock formats via the
programming of the FPINP and CKINP bits in the Internal Mode Selection (IMS) register. By default, the device
accepts the negative input clock format.

ST-BUS Input Timing
When the negative input frame pulse and negative input clock formats are used, the input frame boundary is
defined by the falling edge of the CKi input clock while the FPi is low. When the input data rate is 2.048 Mb/s,
4.096 Mb/s or 8.192 Mb/s, there are 32, 64 or 128 channels per every ST-BUS frame respectively. Figure 7 shows

ST-Bus Output Data Rate and Output Timing
The device has sixteen ST-Bus serial data outputs. Any of the sixteen outputs can be programmed to deliver
different data rates at 2.048 Mb/s, 4.096 Mb/s or 8.192 Mb/s.
2.2.1
ST-Bus Output Operation Mode
Any ST-Bus output can be programmed to deliver the data at 2.048 Mb/s, 4.096 Mb/s or 8.192 Mb/s mode using Bit
0 to 2 in the Stream Output Control Register, SOCR0 to SOCR15 as shown in Table 24 on page 47 and Table 25 on
page 48.
2.2.2
Frame Pulse Output and Clock Output Timing
The device offers three frame pulse outputs, FPo0, FPo1 and FPo2. All output frame pulses are 8kHz output
signals. By default, output frame boundary is defined by the falling edge of the CKo0, CKo1 or CKo2 output clocks
while the FPo0, FPo1 or FPo2 output frame pulse goes low respectively.
In addition to the default settings, users can also select different output frame pulse low cycles and output clock
frequencies by programming the CKFP0, CKFP1 and CKFP2 bits in the Control Register. See Table 2, Table 3 and
Table 4 for the bit usage in the Control Register:

In addition to the input channel delay programming, the input bit delay programming feature provides users with
more flexibility when designing the switch matrices at high speed, in which the delay lines are easily created on
PCM highways which are connected to the switch matrix cards.
By default, all input streams have zero bit delay such that Bit 7 is the first bit that appears after the input frame
boundary, see Figure 16. The input delay is enabled by Bit 0 to 2 in the Stream Input Delay Registers (SIDR). The

Fractional Output Bit Advancement Programming
In addition to the output bit delay, the device is also capable of performing fractional output bit advancement. This
feature offers a better resolution for the output bit delay adjustment. The fractional output bit advancement is useful
in compensating for various parasitic loadings on the serial data output pins.
By default, all output streams have zero fractional bit advancement such that Bit 7 is the first bit that appears after
the output frame boundary as shown in Figure 19. The fractional output bit advancement is enabled by Bit 0 to 1 in

External High Impedance Control, STOHZ 0 to 15
The STOHZ 0 to 15 outputs are provided to control the external tristate ST-BUS drivers for per-channel high
impedance operations. The STOHZ outputs are sent out in 32, 64 or 128 timeslots corresponding to the output
channels for 2.048 Mb/s, 4.096 Mb/s and 8.192 Mb/s output streams respectively. Each control timeslot lasts for
one channel time.
When the ODE pin is high, the STOHZ 0 - 15 are enabled. When the ODE pin or the RESET pin is low, the STOHZ
0 - 15 are driven high. STOHZ outputs are also driven high if their corresponding ST-BUS outputs are not in use.
Figure 20 gives an example when channel 2 of a given ST-BUS output is programmed in the high impedance state,
the corresponding STOHZ pin drives high for one channel time at the channel 2 timeslot.
By default, the output timing of the STOHZ signals follow the same timing as their corresponding STo signals
including any user-programmed output channel and bit delay and fractional bit advancement. In addition, the device
allows users to advance the STOHZ signals from their default positions to a maximum of four 15.2 ns steps (or four
1/4 bit steps) using Bit 3 to 5 of the Stream Output Control Register (SOCR). Bit 6 in the Stream Output Control
Register selects the step resolution as 15.2 ns or 1/4 data bit. The additional advancement feature allows the
STOHZ signals to better match the high impedance timing required by the external ST-BUS drivers.

Data Delay Through The Switching Paths
To maintain the channel integrity in the constant delay mode, the usage of the input channel delay and output
channel delay modes affect the data delay through various switching paths due to additional data buffers. The
usage of these data buffers is enabled by the input and output channel delay bits (STIN#CD6-0 and STO#CD6-0) in
the Stream Input Delay and Stream Output Offset Registers. However, the input and output bit delay or the input
and output fractional bit offset have no impact on the overall data throughput delay.
In the following paragraphs, the data throughput delay (T) is expressed as a function of ST-BUS frames, input
channel number (m), output channel number (n), input channel delay (α) and output channel delay (β). Table 5
describes the variable range for input streams and Table 6 describes the variable range for output streams. Table 7
summarizes the data throughput delay under various input channel and output channel delay conditions.

Connection Memory Description
The connection memory is 12-bit wide. There are 512 memory locations to support the ST-BUS serial outputs
STo0-15. The address of each connection memory location corresponds to an output destination stream number
and an output channel address. See Table 28 on page 51 for the connection memory address map.
When Bit 0 of the connection memory is low, Bit 1 to 7 define the source (input) channel address and Bit 8 to 11
define the source (input) stream address. Once the source stream and channel addresses are programmed by the
microprocessor, the contents of the data memory at the selected address are switched to the mapped output
stream and channel. See Table 29 on page 52 for details on the memory bit assignment when Bit 0 of the
connection memory is low.
When Bit 0 of the connection memory is high, Bit 1 and 2 define the per-channel control modes of the output
streams, the per-channel high impedance output control, the per-channel message and the per-channel BER test
modes. In the message mode, the 8-bit message data located in Bit 3 to 10 of the connection memory will be
transferred directly to the mapped output stream. See Table 30 on page 52 for details on the memory bit
assignment when Bit 0 of the connection memory is high.
2.5.1
Connection Memory Block Programming
This feature allows fast initialization of the entire connection memory after power up. When block programming
mode is enabled, the content of Bit 1 to 3 in the Internal Mode Selection (IMS) Register will be loaded into Bit 0 to 2
of all the 512 connection memory locations. The other bit positions of the connection memory will be loaded
with zeros.
Memory block programming procedure:
(Assumption: The MBPE and MBPS bits are both low at the start of the procedure)
•
Program Bit 1 to 3 (BPD0 to BPD2) in the IMS (Internal Mode Selection) register.
•
Set the Memory Block Programming Enable (MBPE) bit in the Control Register to high to enable the block
programming mode.
•
Set the Memory Block Programming Start (MBPS) bit to high in the IMS Register to start the block
programming. The BPD0 to BPD2 bits will be loaded into Bit 0 to 2 of the connection memory. The other bit
positions of the connection memory will be loaded with zeros. The memory content after block programming
is shown in Table 8.
•
It takes 50µs for the connection memory to be loaded with the bit pattern defined by the BPD0 to BPD2 bits.
•
After loading the bit pattern to the entire connection memory, the device will reset the MBPS bit to low,
indicating that the process has finished.
•
Upon completion of the block programming, set the MBPE bit from high to low to disable the block
programming mode.
Note: Once the block programming is started, it can be terminated at any time prior to completion by setting the
MBPS bit or the MBPE bit to low. If the MBPE bit is used to terminate the block programming before completion,
users have to set the MBPS bit from high to low before enabling other device operation.

Data Sheet
Bit Error Rate (BER) Test
The ZL50012 has one on-chip BER transmitter and one BER receiver. The transmitter can transmit onto a single
STo output stream only. The transmitter provides a BER sequence (215-1 Pseudo Random Code) which can start
from any channel in the frame and lasts from one channel up to one frame time (125 µs). The transmitter output
channel(s) are specified by programming the connection memory location(s) corresponding to the channel(s) of the
selected output stream: Bit 0 to 2 of the connection memory location(s) should be programmed to the BER test
mode (see Table 30 on page 52).
Multiple connection memory locations can be programmed for BER test such that the BER patterns can be
transmitted for several output channels which are consecutive. If the transmitting output channels are not
consecutive, the BER receiver will not compare the bit patterns correctly.
The number of output channels which the BER transmitter occupies also has to be the same as the number of
channels defined in the BER Length Register. The BER Length Register defines how many BER channels to be
monitored by the BER receiver.
Registers used for setting up the BER test are as follows:
•
Control Register (CR) - The CBER bit is used to clear the bit error counter and the BER Count Register
(BCR). The SBER bit is used to start or stop the BER transmitter and BER receiver.
•
BER Start Receiving Register (BSRR) - Defines the input stream and channel from where the BER
sequence will start to be compared.
•
BER Length Register (BLR) - Defines how many channels the sequence will last.
•
BER Count Register (BCR) - Contains the number of counted errors. When the error count reaches Hex
FFFF, the bit error counter will stop so that it will not overflow. Consequently the BER Count Register will
also stop at FFFF. The CBER bit in the Control Register is used to reset the bit error counter and the BER
Count Register.
As described above, the SBER bit in the control register controls the BER transmitter and receiver. To carry out the
BER test, users should set the SBER bit to zero to disable the BER transmitter during the programming of the
connection memory for the BER test. When the BER transmitter is disabled, the transmitter output is all ones.
Hence any output channel whose connection memory has been programmed to BER test mode will also output all
ones. Upon the completion of programming the connection memory for the BER test, set the SBER bit to one to
start the BER transmitter and receiver for the BER testing. They must be allowed to run for several frames (2
frames plus the network delay between STo and STi) before the BER receiver can correctly identify errors in the
pattern. Thus after this time the bit error counter should be reset by using the CBER bit in the Control Register - set
CBER to one then back to zero. From now on, the count will be the actual number of errors which occurred during
the test. The count will stop at FFFF and the counter will not increment even if more errors occurred.

Quadrant frame programming
By programming the input stream control registers (SICR0 to 15), users can divide one frame of input data into four
quadrant frames and can force the Least Significant Bit (LSB, bit 0 in Figure 7 on page 17), of every input channel
in these quadrants into "1" for the bit robbed signaling purpose. The four quadrant frames are defined as shown in
Table 9.

Data Sheet
Microprocessor Port
The device supports the non-multiplexed microprocessor. The microprocessor port consists of a 16-bit parallel data
bus (D0 to 15), a 12-bit address bus (A0 to 11) and four control signals (CS, DS, R/W and DTA). The parallel
microprocessor port provides fast access to the internal registers, the connection and the data memories.
The connection memory locations can be read or written via the 16-bit microprocessor port. On the other hand, the
data memory locations can only be read (but not written) from the microprocessor port.
For the connection memory write operation, D0 to 11 of the data bus will be used and D12 to 15 are ignored (D12 to
15 should be driven low). For the connection memory read operation, D0 to D11 will be used and D12 to D15 will
output zeros. For the data memory read operation, D0 to D7 will be used and D8 to D15 will output zeros.
See Table 28 on page 51 for the address mapping of the data memory. Refer to Figure 36 on page 64 for the
microprocessor port timing.

Device Reset and Initialization
The RESET pin is used to reset the device. When the pin is low, it synchronously puts the device in its reset state.
It disables the STo0 - 15 outputs, drives the STOHZ 0 - 15 outputs to high, clears the device registers and the
internal counters.
Upon power up, the device should be initialized as follows:
•
Set ODE pin to low to disable the STo0-15 output and to drive the STOHZ 0-15 to high.
•
Set the TRST pin to low to disable the JTAG TAP controller.
•
Reset the device by pulsing the RESET pin to low for longer than 1ms.
•
After releasing the RESET pin from low to high, wait for 600 µs for the APLL module to be stabilized before
starting the first microprocessor port access cycle.
•
Program the register to define the frequency of the CKi input.
•
Wait for 600 µs for the APLL module to be stabilized before starting the next microprocessor port access
cycle.
•
Use the memory block programming mode to initialize the connection memory.
•
Release the ODE pin to high after the connection memory is programmed such that bus contention will not
occur at the serial stream outputs STo0-15.
4.0
JTAG Support
The ZL50012 JTAG interface conforms to the Boundary-Scan IEEE1149.1 standard. The operation of the
boundary-scan circuitry is controlled by an external Test Access Port (TAP) Controller.
4.1
Test Access Port (TAP)
The Test Access Port (TAP) accesses the ZL50012 test functions. It consists of three input pins and one output pin
as follows:
•
Test Clock Input (TCK) - TCK provides the clock for the test logic. The TCK does not interfere with any onchip clock and thus remains independent in the functional mode. The TCK permits shifting of test data into or
out of the Boundary-Scan register cells concurrently with the operation of the device and without interfering
with the on-chip logic.
•
Test Mode Select Input (TMS) - The TAP Controller uses the logic signals received at the TMS input to
control test operations. The TMS signals are sampled at the rising edge of the TCK pulse. This pin is
internally pulled to Vdd when it is not driven from an external source.
32
Zarlink Semiconductor Inc.
ZL50012
Data Sheet
•
Test Data Input (TDi) - Serial input data applied to this port is fed either into the instruction register or into a
test data register, depending on the sequence previously applied to the TMS input. Both registers are
described in a subsequent section. The received input data is sampled at the rising edge of TCK pulses.
This pin is internally pulled to Vdd when it is not driven from an external source.
•
Test Data Output (TDo) - Depending on the sequence previously applied to the TMS input, the contents of
either the instruction register or data register are serially shifted out towards the TDO. The data out of the
TDO is clocked on the falling edge of the TCK pulses. When no data is shifted through the boundary scan
cells, the TDO driver is set to a high impedance state.
•
Test Reset (TRST) - Resets the JTAG scan structure. This pin is internally pulled to Vdd when it is not driven
from an external source.
4.2
Instruction Register
The ZL50012 uses the public instructions defined in the IEEE 1149.1 standard. The JTAG Interface contains a fourbit instruction register. Instructions are serially loaded into the instruction register from the TDI when the TAP
Controller is in its shifted-IR state. These instructions are subsequently decoded to achieve two basic functions: to
select the test data register that may operate while the instruction is current and to define the serial test data
register path that is used to shift data between TDI and TDO during data register scanning.
4.3
Test Data Register
As specified in IEEE 1149.1, the ZL50012 JTAG Interface contains three test data registers:
•
The Boundary-Scan Register - The Boundary-Scan register consists of a series of Boundary-Scan cells
arranged to form a scan path around the boundary of the ZL50012 core logic.
•
The Bypass Register - The Bypass register is a single stage shift register that provides a one-bit path from
TDI to its TDO.
•
The Device Identification Register - The JTAG device ID for the ZL50012 is 0C35C14BH.

MBPS
Memory Block Programming Start: A zero to one transition of this bit starts the
memory block programming function. The MBPS, BPD0 to BPD2 bits in this register
must be defined in the same write operation. Once the MBPE bit in the control register
is set to high, the device requires 50 µs to complete the block programming. After the
programming function has finished, the MBPS bit returns to low indicating the operation is completed. When the MBPS is high, the MBPS or MBPE can be set to low to
abort the programming operation.
To ensure proper block programming operation, when MBPS is high the BPD0 to
BPD2 bits in this register must not be changed.
Whenever the microprocessor writes a one to the MBPS bit, the block programming
function is started, the user must maintain the same logical value to the other bits in
this register to avoid any change in the device setting.
