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.
