System Clock In for Ethernet Mapper: 100MHz System Clock
input to the DS33R11, used for internal operation. This clock is
buffered and provided at SDCLKO for the SDRAM interface. The
DS33R11 also provides a divided version output at the REF_CLKO
pin. A clock supply with ±100ppm frequency accuracy is suggested.
Master Clock Input for the T1/E1/J1 Transceiver: A (50ppm)
clock source. This clock is used internally for both clock/data
recovery and for the jitter attenuator for both T1 and E1 modes.
The clock rate can be 16.384MHz, 8.192MHz, 4.096MHz, or
2.048MHz. When using the transceiver in T1-only operation a
1.544MHz (50ppm) clock source can be used.
Backplane Clock from T1/E1/J1 Transceiver: A user-selectable
synthesized clock output that is referenced to the clock that is
output at the RCLKO pin.
Eight Times Clock from the T1/E1/J1 Transceiver: An 8x clock
that is locked to the recovered network clock provided from the
clock/data recovery block (if the jitter attenuator is enabled on the
receive side) or from the TDCLKI pin (if the jitter attenuator is
enabled on the transmit side).
Quartz Crystal Driver for the T1/E1/J1 Transceiver: A quartz
crystal of 2.048MHz (optional 1.544MHz in T1-only operation) can
be applied across MCLK and XTALD instead of a clock source at
MCLK. Leave open circuited if a clock source is applied at MCLK.
