Receiver Functional Description
The MC92610 receiver is based upon an oversampled transition tracking loop data recovery
method. The receiver receives differential data in one of two operating ranges. It may be
operated in full rate range with a maximum data rate of 2.5 Gbps (3.125 gigabaud) or at
half-rate at 1.25 Gbps (1.5625 gigabaud). The operating range is determined by the state of
the HSE input.
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
ten-bit interface (TBI) mode.
REF_CLK_P/N
PLL Reference Clock
PLL input reference clock. Provides
reference frequency for the receiver
interface when Recovered Clock mode
is disabled (RCCE is low).
Input
-
ADIE
Add/Delete Idle Enable
Indicates that the receiver is free to
add/delete Idle characters to/from the
output data stream to maintain
alignment.
Input
High
REPE
Repeater Mode Enable
When enabled, the transmitter obtains
transmit data from the receiver.
