Overview
The CY7C9538 (POSIC2GVC-R™) is a highly integrated
SONET/SDH framer device for transport of ATM and IP
packets over SONET/SDH links. It features special functions
and architecture to support next-generation optical networking
protocols for both SONET/SDH and direct data-over-fiber
networks. POSIC2GVC-R offers enhanced virtual concatenation support that permits dynamic reconfiguration of channel
bandwidth during operation.
POSIC2GVC-R performs complete SOH, LOH, and POH
processing. Complete access to all overhead bytes is provided
through register access via the host CPU interface. Access to
selected overhead bytes are also available through serial port.
Optional frame sync input and Transport Overhead (TOH)
bypass enables better interface with STS-1 switched streams.
The virtual concatenation feature, with up to 16 channels,
enables provisioning of secure, dedicated and right-sized
bandwidth for Ethernet or ATM transport. Up to 16 virtual
channels can be created with STS-1 or STS-3c granularity.
Bandwidth from 50 Mbps to 1.2 Gbps can be allocated per
channel.
POSIC2GVC-R supports packet over SONET/SDH as PPP in
HDLC-like frame as per IETF rfc 1619/1662/2615 (PPP).
POSIC2GVC-R also supports full duplex ATM over
SONET/SDH transport in compliance with ITU I432.2.
POSIC2GVC-R supports the new generation Generic Framing
Procedure (GFP) protocol encapsulation/Decapsulation over
SONET/SDH. This protocol engine features wire rate framing,
frame delineation and deframing with length-CRC pair header
construct. Optional payload scrambling/descrambling and
payload FCS are also provided.
Clear channel mode enables transport of any raw byte
streams on selected virtual channels, while the rest of the
channels are transporting data through any one of encapsulation/decapsulation engines.
The Programmable Frame Tagging Engine enables wire rate
tagging of packets/frames. For new generation networking
features such as MPLS, this engine can be programmed to tag
based on existence/lack of specific label/field values, in the
first 64 bytes of each packet. This way, packets are tagged for
a variety of conditions, all programmable by the user, enabling
sorting of packets in the incoming data stream and buffering
packets accordingly. In a PPP application, control packets can
optionally be sent over the host CPU interface directly.
OIF-SPI (POS-PHY) level 3, UTOPIA level 3 and
High-Bandwidth Synchronous Transfer (HBST) interfaces are
provided on the system side.
SONET/SDH bypass mode allows use of this device for data
transport in non SONET/SDH point-to-point and mesh optical
networks.
Transmit
In the transmit direction, packets are received from the system
side, encapsulated/framed and mapped into the SONET/SDH
payload. Finally the TOH is added and SONET/SDH frames
are passed onto the fiber side/line side interface on a parallel
bus.
The system side interface can be programmed either as
OIF-SPI level 3, or UTOPIA level 3 or HBST modes. In the
UTOPIA mode, ATM cells can be received either in 54- (8-bit
Document #: 38-02095 Rev. *B
CY7C9538
interface) or 56- (8-bit and 32-bit interfaces) bytes format. The
sixth byte carries the channel number of the cell. In case of
packets, the interface can be programmed as OIF-SPI level 3
or HBST operations. In these cases, the first data transfer
always carry the channel number.
POSIC2GVC-R supports three basic types of encapsulation,
namely (i) ATM, (ii) HDLC frame, and (iii) GFP (frames with
length-CRC pair header construct based delineation). Clear
channel or transparent mode (no encapsulation) is also
supported. While in operation, only one type of encapsulation
can be enabled for all VC channels. Some or all of the VC
channels can be programmed as clear channels. For Clear
Channels, the encapsulator engine will bypass the encapsulation and pass the packets without any processing to the next
block.
Encapsulated packets are transferred to the Virtual Concatenation (VC) block along with the channel number. The VC
block rearranges the packet/frame flow to support the
bandwidth allocation for virtual channels. Bandwidth is
assigned by allocating a programmed number of SPEs to each
channel. The VC block keeps track of the SPE under
construction by the SONET/SDH framer block and transfers
the packets meant for a given channel to the SONET framer.
Since POSIC2GVC-R does not have a packet storage
memory on-chip, a channel bandwidth balanced packet flow is
expected from the system side. To enable such a balanced
transfer, POSIC2GVC-R has internal FIFO of 512 bytes per
channel. The status of FIFO is provided through pins to the link
layer.
Finally, the SONET/SDH framer inserts the packet /cells into
the SONET/SDH frame. All overhead bytes are added. All
alarm bits and status bits are inserted based on the status of
incoming frames as well as programming done by the host
CPU. The scrambler meets relevant standards and can
optionally be disabled. Frames are finally sent out on the fiber
side interface. If programmed to do so, the SONET/SDH
framer can be bypassed and encapsulated packets/frames
can be sent directly to the fiber-side interface.
Receive
In the receive direction, SONET/SDH frames are received
from the fiber side. Data packets/frames are extracted from the
payload and passed onto the selected decapsulator engine
after compensation for differential delay, in case of virtual
concatenation. If the SONET/SDH framer is bypassed, the
incoming data stream is directly passed over to the decapsulator engine. Data packets/frames are then decapsulated and
sent to the Programmable Frame Tagging Engine. They are
then analyzed and tagged before sent out to the system side
via the OIF-SPI level 3, UTOPIA or HBST interface. Tagging
of frames is optional.
SONET/SDH frames entering from the fiber side are synchronized and the frame boundary is identified with A1A2 bytes.
Frames
can
be
optionally
synchronized
with
Frame_Sync_Input to identify the boundary. Descrambling is
performed to retrieve scrambled frames. Complete processing
of all overhead bytes, Section, Line and Path, is performed
and all alarm bits are verified and alarms are raised as
programmed. Full access to all overhead bytes is provided
through register access. Access to selected overhead bytes is
also provided through serial bus. The SONET/SDH deframing
can be entirely bypassed.

The extracted payload is transferred to the VC block where it
is reorganized to compensate for any differential delay
encountered in the network from the virtual concatenation
channel. For this purpose, up to 256 frames are stored in
external memory. The VC block then passes the payload
stream to the selected decapsulator engine.
Table 1. Virtual Concatenated Channel Bandwidth[16]
The selected decapsulator engine delineates the payload
stream, decapsulates and extracts packets/cells from the
stream. Descrambling of packets/cells is optional. The
packets/cells are then sent out to the programmable Frame
Tagging Engine.
The Frame Tagging Engine optionally tags the packet/cell as
programmed. The packet/cell is then transferred to the link
layer device, through the System Interface (OIF-SPI/UTOPIA
level 3, or HBST), with an additional eight bits of information.
Four bits specify the VC channel and the other four bits specify
the tag.
Reconfigurable Virtual Concatenation
Virtual concatenation creates multiple virtual payloads of
different sizes within the incoming SONET/SDH frame, effectively creating multiple channels of different bandwidth.
The advantages of VC are:
• Efficient and dedicated bandwidth allocation.
• Compatibility with TDM access infrastructure. Virtually
concatenated channels can coexist with aware and
nonaware Network Elements on the same shared access.
• Independence from upper layer data protocol/frame format.
• Fine granularity channels are extensible and easily provisionable.
Virtual concatenation requires specific overhead processing
capabilities only at the path terminating equipment. It remains
transparent at the intermediate nodes in the network. It is
possible therefore that two or more different SPEs, virtually
bonded to create a channel, travel through different routes in
the network. Hence, they can arrive at the destination in the
order different from the order at the point of origination. Delay
encountered in arrival of two virtually concatenated SPEs in a
frame is called differential delay. To compensate for differential
delay, the SPE received earlier need to be stored until the
particular SPE, which is previous in the order but faces longer
travel time, arrives at the terminating node. POSIC2GVC-R
can store up to 256 SONET/SDH frames in external memory,
which can compensate for ±16 ms of differential delay. For
differential delay higher than that, POSIC2GVC-R raises an
alarm.
POSIC2GVC-R supports VC for all types of packets/frames/
protocols it transports on SONET/SDH. VC mode is supported
at OC-48/STM-16 and OC-12/STM-4 line rates. Table 1 shows
a list of virtually concatenated channel bandwidth supported
by POSIC2GVC-R. Up to 16 channels can be created using
STS1/VC-3,
STS3c/VC-4,
STS12c/VC4-4c
and
STS24c/VC4-8c. Further, unused line bandwidth (tributaries
not assigned to any active channel) can remain unassigned.
This allows all of the 16 channels (max) to be assigned to valid
equipped traffic.

POSIC2GVC-R allows dynamic reconfiguration of VC channel
bandwidth. Only the channels that are involved in reconfiguration may see transitory traffic disruption resulting from this
bandwidth modification. Traffic in all other channels are
unaffected. This permits on-the-fly reprovisioning in high-availability applications.
Dynamic reconfiguration allows the number of tributaries of a
VC channel to increase or decrease. For example, if originally
Chan0 is STS1-4v and Chan1 is STS1-2v, a 50Mbps dynamic
reconfiguration step programming can change the channel
bandwidth to: Chan0 = STS1-3v, Chan1 = STS1-3v. There are
no limitations to VC channel bandwidth change as long as the
maximum channel bandwidth is not exceeded, SONET/SDH
mapping is not violated, and there exists enough tributaries of
the required type (e.g., STS1 or STS3c) from initial
POSIC2GVC-R configuration.
Dynamic reconfiguration allows VC channels to be added or
removed on-the-fly. Bandwidth reassigned from a dropped
channel can be transferred to an existing active channel, a
new added channel, or to the pool of unassigned bandwidth.
Further, the POSIC2GVC-R transmit side supports dynamic
change of tributary assignments in the transmitted
SONET/SDH frames by the slot programming feature. This
allows the slot positions of individual tributaries to be
customized. Combined with dynamic reconfiguration, the
POSIC2GVC-R transmit side permits a change of VC channel
type from STS1/VC3 to STS-3c/VC4 or vice versa. Unrelated
channels are unaffected by the change.
The POH serial access port of POSIC2GVC-R can be interfaced to external control logic to provide LCAS signaling
capability over SONET/SDH H4 bytes. For more information,
please see the Cypress application note Emulating LCAS
using POSIC2GVC-R.
Note:

Generic Frame Encapsulation/Decapsulation
POSIC2GVC-R supports a variety of protocol/packets/frames
to transport over a SONET/SDH link. For clarity of reference,
in this document, framing of packets/cells into these protocols
is called “encapsulation,” and the engine performing encapsulation is called an “encapsulator.” Similarly, deframing is called
“decapsulation,” and the engine performing decapsulation is
called a “decapsulator.”
Three different encapsulator and decapsulator engines are
integrated into POSIC2GVC-R.
The ATM encapsulator computes and adds the HEC field,
scrambles the cells and passes on to the VC block. In case of
underflow, ATM encapsulator also creates programmable idle
cells.
The ATM decapsulator checks for HEC and integrity of the cell.
It descrambles the cells, isolates and discards idle cells and
passes ATM cells to the Programmable Frame Tagging
Engine.
HDLC encapsulator performs Asynchronous Control
Character Mapping (ACCM), stuffing, flag sequence insertion
and scrambling. Optionally, up to 16 bytes of header is inserted
ahead of the packet while framing the packet. The host CPU
can program this 16-byte header through register programing.
CY7C9538
Such programmable header insertion enables encapsulation
of PPP, frame relay or other protocol.
The HDLC decapsulator descrambles the incoming byte
stream and searches the flag sequence. Upon finding the
boundary, decapsulator performs destuffing and ACCM
demapping before passing the packets to the Programmable
Frame Tagging Engine.
The Generic Framing Procedure (GFP) Encapsulator/Decapsulator supports delineation based on length-CRC pair header
construct. In the transmit direction, it computes a 16-bit header
CRC based on 2-byte length value received from the link layer
device. The length and CRC fields are inserted as header of
the frame ahead of the packet. Scrambling of the payload and
32-bit payload CRC computation and insertion are optional.
In the receive direction, GFP frames are delineated based on
the length-CRC construct pair header, integrity verified,
payload extracted, optionally descrambled and sent to the
Programmable Frame Tagging Engine.
Any selected VC channel can be programmed to become a
‘clear channel’. The encapsulator and decapsulator remain in
transparent mode for the clear channel and data passes
through without any modification. This feature can be used to
transport any raw data streams on a portion of bandwidth while
the rest of the bandwidth is utilized for protocol traffic.

Programmable Frame Tagging Engine
The Programmable Frame Tagging Engine provides preclassification of the packets/frames at the wire rate. This helps in
utilizing the link layer device more efficiently.
The Programmable Frame Tagging Engine enables the user
to perform preclassification of all the incoming packets into
one of the 16 possible categories. Since each channel can
have up to 16 different categories, and up to 16 virtual concatenated channels are possible, this engine supports up to 256
different categories. For classification, two-pass comparison
can be specified. For each comparison a field of up to six bytes
can be selected within the first 64 bytes of the packet and
compared with up to 16 programmed values. The comparison
is on a bit by bit basis and any bit comparison can be masked
with a user programmable mask register. A four-bit tag is
attached to the cell/packet, based on the match. Host CPU can
program these parameters through register programming.
CY7C9538
The following drawing demonstrates one possible combination of classification with the help of the Programmable
Frame Tagging Engine.
The following functions can be achieved with the help of the
Programmable Frame Tagging Engine:
Incoming packet analysis to parse packets/frames/cells at wire
speed.
User-programmable routing of control packets to CPU for
processing.
Incoming frames tagged based on bits (such as congestion) in
incoming packets.
User-programmable offset to locate Ethernet and other frames
within DOS and other proprietary MAN networking protocols
to allow MPLS processing.

SONET/SDH Bypass
POSIC2GVC-R supports the SONET/SDH framer/deframer
bypass mode. Host CPU can program such bypass. In this
mode, the data frames/packets, encapsulated by one of the
encapsulators, will be transmitted transparently through VC
and SONET/SDH blocks to the fiber side and vice versa.
System Interface
The system interface is programmable. For application in an
ATM system, POSIC2GVC-R system interface can be
programmed to be PHY side interface as per UTOPIA level 3
specifications.
For variable length packets, POSIC2GVC-R system interface
can be programmed to be OIF-SPI level 3. ATM cells can also
be transferred over OIF-SPI level 3 bus.
System interface can be programmed in HBST mode. In this
case, a separate set of address pins are supported on the
system side. This mode supports high-speed burst access.
CPU Interface
CY7C9538
protection switching with only one device being main and
connected to link layer. The standby POSIC2GVC-R device is
connected to the main POSIC2GVC-R device and it is
controlled by host CPU. POSIC2GVC-R provides APS byte
information to the host CPU. The host CPU is expected to take
a protection switching decision and provide necessary instructions to both POSIC2GVC-R devices.
In case of protection switching, in the transmit direction, the
main POSIC2GVC-R will perform all other operations as
programmed, except some of the line and section processing
of SONET/SDH framing. The main POSIC2GVC-R device will
then pass on the SPEs to the standby device through the APS
port. The standby device will then perform the rest of the line
and section processing and transport SONET/SDH frames
over standby fiber.
Similarly, in case of protection switched mode, on the receive
side, the standby device will process some of the line and
section overhead and transfer the frames to main device
through the APS port. The main device will perform the rest of
the processing in the receive side.
RxS
POSIC2GVC-R can interface with 16-bit or 32-bit CPU. The
CPU interface can be pin configured to be compatible with
Motorola or Intel bus interface. The CPU interface provides
access to all registers of POSIC2GVC-R, collates all interrupt
generated by various blocks and also supports control packet
transfers.

Figure 5. POSIC2GVC-R APS Implementation using
Two POSIC2GVC-R Devices
Single Framer APS Implementation
A main and slave PHY device can be interfaced directly to the
main and APS ports of a single POSIC2GVC-R device. In this
case, the main PHY is connected to the main line interface and
the standby PHY is connected to the APS port.
In the POSIC2GVC-R transmit path, SONET/SDH data is
bridged across the main and APS ports (per linear 1+1 APS
requirements). When protection switching, POSIC2GVC-R
can be programmed to switch line inputs from the main receive
port to the APS receive port, or vice versa.
This APS scheme provides solely optical/PHY link level
protection.

indicates that transmit FIFO is full or near full (user programmable).
STPA always provides status indication for the selected channel in
order to avoid FIFO overflows while polling is performed.
STPA is three-stated when TENB is deasserted in the previous cycle.
STPA is also deasserted when either the null-port address (0x1F) or
an address not matching the POSIC2GVC-R address is presented on
the TADR[3:0] signals when TENB is sampled HIGH (has been
de-asserted during the previous clock cycle).
STPA is mandatory only if packet-level transfer mode is supported. It
is not be driven in byte-level mode.
ATM:
There is no corresponding pin definition in ATM mode, however, this
pin will output the same signal as STPA in POS mode
HBST:
FIFO Available Status (TSTFA) signal.
FIFO available status of the selected port is reflected on this pin two
clocks after detecting the port address when the TDVAL signal is
active.
PTCA
O LVTTL
1
N
POS:
Polled-Port Transmit Packet Available (PTPA) signal.
PTPA transitions HIGH when a predefined (user-programmable)
minimum number of bytes are available in the polled transmit FIFO.
Once HIGH, PTPA indicates that the transmit FIFO is not full. When
PTPA transitions LOW, it optionally indicates that transmit FIFO is full
or near full (user-programmable). PTPA allows polling the
POSIC2GVC-R channel selected by TADR[3:0] when TENB is
asserted.
PTPA is driven by a POSIC2GVC-R when its address is polled by
TADR[3:0]. POSIC2GVC-R will three-state PTPA when either the
null-port address (0x1F) or an address not matching POSIC2GVC-R
is provided on TADR[3:0].
PTPA is mandatory only if in packet-level transfer mode. It will not be
driven in byte-level mode.
ATM:
UTOPIA Transmit Cell Available (TxClav)
The TxClav signal indicates when a cell is available in the transmit
FIFO for the port polled by TxAddr[3:0] when TxEnb* is asserted.
When HIGH, TxClav indicates that the corresponding transmit FIFO
is not full and a complete cell may be written. When TxClav goes LOW,
it can be configured to indicate either that the corresponding transmit
FIFO is near full or that the corresponding transmit FIFO is full. TxClav
is three-stated when either the null-Port address (0x1F) or an address
not matching the address space set is latched from the TxAddr[4:0]
inputs when TxEnb* is HIGH.
TxClav is updated on the rising edge of TxClk.
HBST:
FIFO Available status on TFAST bus (TSOFST) signal.
Active HIGH pulse indicates the start of FIFO available status on
TFAST bus. This signal is repeated once in every four clocks.
TSX
I
1
N
POS:
Transmit Start of Transfer (TSX) signal.
TSX indicates inband port address on the TDAT bus. When TENB is
HIGH and TSX is asserted (HIGH), the value of TADR[3:0] is the
address of transmit FIFO selected.
TSX is valid only when TENB is deasserted.

Synchronous Write Enable Input, active LOW.
This must be sampled on the rising edge of CLK if CEN is active LOW.
This signal must be asserted LOW to initiate a write sequence
ADV/LD
O LVTTL

N
Synchronous Advance/Load Input
This pin is used to advance the on-chip (SRAM’s) address counter or
load a new address. When HIGH (and CEN is asserted LOW) the
internal burst counter of SRAM is advanced. When LOW, a new
address is loaded into the SRAM for an access.
After being deselected, ADV/LD should be driven LOW in order to load
a new address.

N
Asynchronous Output Enable, active LOW.
This pin controls the direction of the I/O pins. When LOW, the I/O pins
behave as outputs for SRAM. When deasserted HIGH, I/O pins are
three-stated, and act as input data pins by the SRAM. OE is masked
during the data portion of a write sequence, during the first clock when
emerging from a deselected state, when the device has been
deselected.
DQ1[31:0]
I/O LVTTL
32
N
Synchronous Bidirectional Data I/O lines for SRAM1.
As inputs to SRAM, these pins feed into a data register that is triggered
by the rising edge of CLK. As outputs from SRAM, they deliver the data
contained in the memory location specified by A [18:0] during the
previous clock rise of the read cycle. When OE is asserted LOW, the
pins can behave as outputs from SRAM. When HIGH, DQ1 [31:0] are
placed in a three-state condition by the SRAM. The outputs are
automatically three-stated during the data portion of a write sequence,
during the first clock when emerging from a deselected state, and
when the device is deselected, regardless of the state of OE.
DQ2 [31:0]
I/O LVTTL
32
N
Synchronous Bidirectional Data I/O lines for SRAM2.
As inputs to SRAM, these pins feed into a data register that is triggered
by the rising edge of CLK. As outputs from SRAM, they deliver the data
contained in the memory location specified by A [18:0] during the
previous clock rise of the read cycle. When OE is asserted LOW, the
pins can behave as outputs from SRAM. When HIGH, DQ2 [31:0] are
placed in a three-state condition by the SRAM. The outputs are
automatically three-stated during the data portion of a write sequence,
during the first clock when emerging from a deselected state, and
when the device is deselected, regardless of the state of OE.

Reset Requirements
Asserting the RST_n signal will asynchronously reset all
sequential elements of POSIC2GVC-R. Even though the reset
is treated as asynchronous signal, it is recommended that a
minimum of 1-ms-wide active LOW RST_n is applied after all
power supplies have stabilized.
CY7C9538
There is no particular power-up sequence requirements
among VCC1, VCC2, and VCC3 in this case.
There is no particular power-up sequence requirements
among VCC1, VCC2, VCC3, and VCC5 if HSTL I/O is not used.
RST_n needs to be activated until all the power supplies have
stabilized.
AC and Timing Specifications
Power-Up Requirements
When HSTL I/O is used, VCC1, VCC2, and VCC3 need to be
powered up first before VCC5 supply. VCC5 shall be powered
up at least 300ms after the last of the other power supplies.
The POSIC2GVC-R device interfaces to industry standard
peripheral devices or buses. Hence the POSIC2GVC-R pin
timing parameters are governed by the interface requirements
of the peripherals or the relevant standards. Table 7 details the
timing requirements.
