description (continued)
The intended application of this device is to provide building blocks for developing point-to-point baseband data transmission over controlled-impedance media of approximately 50 Ω to 75 Ω. The transmission media can be printed-circuit board traces, back planes, cables, or fiber optical media. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment.
The SN75FC1000B performs the data serialization and deserialization (SERDES) functions for the fibre channel physical layer interface. The transceiver operates at 1.0625 Gbps (typical), providing up to 100 MBps of bandwidth over a copper or optical media interface. The serializer/transmitter accepts 8b/10b parallel encoded data bytes. The parallel data bytes are serialized and transmitted differentially nonreturn-to-zero (NRZ) at pseudo-ECL (PECL) voltage levels. The deserializer/receiver extracts clock information from the input serial stream and deserializes the data, outputting a parallel 10-bit data byte. The 10-bit data bytes are output with respect to two receive byte clocks (RBC0, RBC1) allowing a protocol device to clock the parallel bytes in RBC clock rising edges.
The transceiver automatically locks onto incoming data without the need to prelock. However, the transceiver can be commanded to lock to the externally supplied reference clock (REFCLK) as a reset function, if needed.
The SN75FC1000B provides an internal loopback capability for self-test purposes. Serial data from the serializer is passed directly to the deserializer allowing the protocol device a functional self-check of the physical interface.
The SN75FC1000B is characterized for operation from 0°C to 70°C.

DESCRIPTION
I/O and DATA
DOUT_TXP DOUT_TXN
62 61
Output Differential output transmit. DOUT_TXP and DOUT_TXN are differential serial outputs that interface
to a copper or an optical I/F module. These terminals transmit NRZ data at a rate of 1.0625 Gbps. DOUT_TXP and DOUT_TXN are held static when LOOPEN is high and are active when LOOPEN is low .
DIN_RXP DIN_RXN
54 52
Input Differential input receive. DIN_RXP and DIN_RXN together are the differential serial input interface
from a copper or an optical I/F module. These terminals receive NRZ data at a rate of 1.0625 Gbps and are active when LOOPEN is held low.
LCKREFN 27 Input Lock to reference. When LCKREFN is asserted low, the receive PLL phase locks to the supplied
REFCLK signal. LCKREFN prelocks or resets the receive PLL.
LOOPEN 19 Input Loop enable. When LOOPEN is high (active), the internal loop-back path is activated. The
transmitted serial data is directly routed to the inputs of the receiver. This provides a self-test capability in conjunction with the protocol device. The DOUT_TXP and DOUT_TXN outputs are held static during the loop-back test. LOOPEN is held low during standard operational state with external serial outputs and inputs active.
RBC0 RBC1
31 30
Output Receive byte clock. RBC0 and RBC1 are 53.125-MHz recovered clocks used for synchronizing the
10-bit output data on RD0 – RD9. The 10-bit output data words are valid on the rising edges of RBC0 and RBC1. These clocks are adjusted to half-word boundaries in conjunction with synchronous detect. The clocks are always expanded during data realignment and never slivered or truncated. RBC0 registers bytes 1 and 3 of received data. RBC1 registers bytes 0 and 2 of received data.
RC1, RC0
49 48
Analog Receive capacitor. RC0 and RC1 are external capacitor connections used for the receiver internal
PLL filter. The recommend value for this external capacitor is 2 nF.
RD0 – RD9 45,44,43,41,
40,39,38,36,
35,34
Output Receive data. These outputs carry 10-bit parallel data output from the transceiver to the protocol
layer. The data is referenced to terminals RBC0 and RBC1. Received data byte 0, which contains the K28.5 character, is byte aligned to the rising edge of RBC1. RD0 is the first bit received.
REFCLK 22 Input Reference clock. REFCLK is an external 106.25 MHz input clock that synchronizes the receiver and
transmitter interfaces. The transmitter uses this clock to register the 10-bit input data (TD0..TD9) for serialization. REFCLK is also used as a RX PLL preset or reference when LCKREFN is enabled.
SYNC 47 Output Synchronous detect. SYNC is asserted high upon detection of the K28.5 character in the serial data
path. SYNC is a high level for 1/2 REFCLK period. SYNC pulses are output only when SYNCEN is activated (asserted high).
SYNCEN 24 Input Synchronous function enable. When SYNCEN is asserted high, the internal synchronization
function is activated. When this function is enabled, the transceiver detects the K28.5 character (0011111010 negative beginning disparity) in the serial data stream and realigns data on byte boundaries if required. When SYNCEN is low, serial input data is unframed in RD0 – RD9.
TC1 TC0

detailed description
data transmission
The transmitter registers incoming 10-bit-wide data words (8b/10b encoded data, TD0 – TD9) on the rising edge of REFCLK (106.25 MHz). The reference clock is also used by the serializer, which multiplies the clock by a factor of 10 providing a 1.0625 Gbaud signal that is fed to the shift register. The data is then transmitted differentially at PECL voltage levels. The 8b/10b encoded data is transmitted sequentially bit 0 through 9.
transmission latency
The data transmission latency of the SN75FC1000B is defined as the delay from the initial 10-bit word load to the serial transmission of bit 9. The typical transmission latency is 13 ns.
data reception
The receiver of the SN75FC1000B deserializes 1.0625 Gbps differential serial data. The 8b/10b data (or equivalent) is retimed based on an extracted clock from the serial data. The serial data is then aligned to the 10-bit word boundaries and presented to the protocol controller along with two receive byte clocks (RBC0, RBC1). RBC0 and RBC1 are 180 degrees out of phase and are generated by dividing down the recovered
1.0625 Gbps (531 MHz) clock by 10 providing for two 53-MHz signals. The receiver presents the protocol device byte 0 of the received data valid on the rising edge of RBC1.
NOTE:
This allows the option of byte alignment without the use of the synchronous detection (SYNC) function by the protocol device.
The receiver PLL can lock to the incoming 1.0625 GHz data without the need for a lock-to-reference preset. The received serial data rate (RX+ and RX–) should be 1.0625 Gbps ±0.01% (100 ppm) for proper operation.

data reception (continued)
During a bus error condition or word alignment, the receive byte clocks RBC0 and RBC1 are stretched (never truncated), ensuring that their frequency never exceeds 60 MHz. When the incoming serial data does not meet its frequency requirements, then the receive byte clock frequency is maintained and never exceeds 60 MHz.
receive PLL operation
The receive PLL provides automatic locking to the incoming data. At power up, the maximum initial lock time is 500 µs. The PLL can also be initiated or set to phase lock to the externally supplied reference clock by enabling lock-to-reference (LCKREFN). The lock-to-reference causes the receive PLL to lock to 10× the reference clock (REFCLK) input providing a PLL preset and reset capability.
If during normal operation a transient occurs, which is defined as any arbitrary phase shift in the incoming data and/or a frequency wander of up to 200 ppm, then the PLL recovers lock within 2.4 µs (2500 serial bit times). Any condition exceeding these values is considered a power-up scenario and the PLL recovers lock within 500 µs.
receiver word alignment
The SN75FC1000B uses a 10-bit K28.5 character (comma character) word alignment scheme. The following sections explain how this scheme works and how it realigns itself.
comma character on expected boundary
The SN75FC1000B provides 10-bit K28.5 character recognition and word alignment. The 10-bit word alignment is enabled by forcing SYCNEN high. This enables the function that examines and compares ten bits of serial input data to the K28.5 synchronization character. The K28.5 character is defined in the fibre channel standard as a pattern consisting of 0011111010 (a negative number beginning disparity) with the 7 MSBs (0011111) referred to as the comma character. The K 28.5 character was implemented specifically for aligning fibre channel data words. As long as the K28.5 character falls within the expected 10-bit word boundary , the received 10-bit data is properly aligned and data realignment is not required. Figure 1 shows the timing characteristics of RBC0, RBC1, SYNC and RD0 – RD9 while synchronized.
NOTE:
The
K28.5 character is valid on the rising edge of RBC1.

comma character not on expected boundary
When synchronization is enabled and a K28.5 character straddles the expected 10-bit word boundary, then word realignment is necessary. Realignment or shifting the 10-bit word boundary truncates the character following the misaligned K28.5, but the following K28.5 and all subsequent data is aligned properly as shown in Figure 2. The 10b specification requires that RCLK cycles can not be truncated and can only be stretched or stalled in their current state during realignment. With this design the maximum stretch that occurs is an extra 10 bit times. This occurs during a worst case scenario when the K28.5 is aligned to the falling edge of RBC1 instead of the rising edge. Fibre channel compliant systems transmit a minimum of three consecutively ordered K 28.5 data sets between frames and ensure that the receiver sees at least two of K28.5 sets (the fabric is allowed to drop one). Figure 2 shows the timing characteristics of the data realignment.
Systems that do not require framed data can disable byte alignment by tying SYNCEN low. When a synchronization character is detected the SYNC signal is asserted high and is aligned with the K28.5
character. The duration of the SYNC-signal pulse is equal to the duration of the data which is half an RCLK period.

data reception latency
The serial-to-parallel data latency is the time from when the first bit arrives at the receiver until it is output in the aligned parallel word with RD0 received as first bit. The receive latency is typically 21 ns.
loop-back testing
The transceiver can provide a self-test function by enabling (LOOPEN to high level) the internal loop-back path. Enabling LOOPEN causes serially transmitted data to be routed internally to the receiver. The parallel data output can be compared to the parallel input data for functional verification. The external differential output is held in a static state during loop-back testing.

MECHANICAL INFORMATION
The SN75FC1000B incorporates the latest development in TI’s package line. The new patent-pending design, designated the PWP delivers thermal performance comparative to a heat-spreader design in a true low-profile package. The PWP, for the SN75FC1000B is designed to maximize heat transfer away from the die through the top of the chip. As seen in Figures 9 and 10 the bottom of the leadframe is deep downset towards the top of the chip, providing a thermal path away from the die and board. All this has been accomplished without exceeding the 1.15 mm height of the TQFP . This package in the 10mm × 10mm TQFP (PJD) provides a thermal resistance R
θJA
of 40°C/W and the package in the 14mm × 14mm TQFP (PHD) provides a R
θJA
of 40°C/W.
