Functional Description
half-rate at 500 Mbps (0.625 gigabaud). The operating range is determined by the state of
the HSE input and the frequency of the reference clock, see Table 5-1.
Transmitted data is recovered using an oversampled transition tracking method. The
received serial data is accumulated into ten-bit characters. The ten-bit characters are
forwarded to the 8B/10B decoder where the original data is obtained. Alternately, the
decoder can be bypassed and the ten-bit character is forwarded to the Receiver Interface in
the ten-bit interface (TBI) mode.
The receiver provides for byte (character) alignment. Alignment assures that the byte as
presented at the input of the transmitter is preserved when the byte is presented by the
receiver. Optionally, alignment may be disabled.
The receiver also provides for word synchronization. In this mode, all of the receivers are
being used cooperatively to receive 32-bit (40 bit in TBI mode) words. Word
synchronization assures that the receivers present the four bytes of a word simultaneously.
The Receiver Interface, where the received bytes and status codes are obtained, has several
modes of operation and timing to allow it to be used in a variety of applications. The
following sections provide a detailed description of the receiver and its modes of operation.
3.3.1
Input Amplier
The input ampliers connect directly to the link input pads RLINK_x_P and RLINK_x_N.
It is a differential amplier with integrated analog multiplexer for loop-back testing. Link
termination resistors are integrated with the amplier. The termination resistance is either
100
or 150 differential depending upon the state of the MEDIA input.
The input amplier facilitates a loop-back path for production and in-system testing. When
the MC92602 is in loop-back mode (Loop Back Enable, LBE, is high), the input amplier
selects the loop-back differential input signals and ignores the state on the RLINK_x_P and
RLINK_x_N signals. This allows in-system loop-back BIST independent of the current
input state. See Chapter 6 for more information on test modes.
3.3.2
Transition Tracking Loop and Data Recovery
The received differential data from the input amplier is sent to the transition tracking loop
for data recovery. The MC92602 uses an oversampled transition tracking loop method for
data recovery. The differentially received data is sampled and processed digitally providing
for low bit error rate (better than 10 -12) data recovery of a distorted bit stream.
The transition tracking loop is tolerant of frequency offset between the transmitter and
receiver. The MC92602 reliably operates with +250 ppm of frequency offset. The transition
tracking loop method is different than the typical PLL clock recovery method. Its receiver
compensates for overrun and underrun due to frequency offset by modulating the
