Write Input [ WR ] (Read/Write [R/ W ]). WR is an active low signal.
LINE INTERFACE PINS
Master Clock Input [MCLK]. A 1.544 MHz (± 50 ppm) clock source with TTL levels is applied at this
pin. This clock is used internally for both clock/data recovery and for jitter attenuation. A quartz crystal
of 1.544 MHz may be applied across MCLK and XTALD instead of the TTL level clock source.
Quartz Crystal Driver [XTALD]. A quartz crystal of 1.544 MHz may be applied across MCLK and
XTALD instead of a TTL level clock source at MCLK. Leave open circuited if a TTL clock source is
applied at MCLK.
Eight Times Clock [8XCLK]. A 12.352 MHz clock that is frequency locked to the 1.544 MHz clock
provided from the clock/data recovery block (if the jitter attenuator is enabled on the receive side) or from
the TCLKI pin (if the jitter attenuator is enabled on the transmit side). Can be internally disabled via the
TEST2 register if not needed.
Line Interface Connect [LIUC]. Tie low to separate the line interface circuitry from the
framer/formatter circuitry and activate the TPOSI/TNEGI/TCLKI/RPOSI/RNEGI/RCLKI pins. Tie high
to connect the line interface circuitry to the framer/formatter circuitry and deactivate the
TPOSI/TNEGI/TCLKI/RPOSI/RNEGI/RCLKI
pins.
When
LIUC
is
tied
high,
the
TPOSI/TNEGI/TCLKI/RPOSI/RNEGI/RCLKI pins should be tied low.
Receive Tip and Ring [RTIP & RRING]. Analog inputs for clock recovery circuitry. These pins
connect via a 1:1 transformer to the T1 line. See Section 14 for details.
Transmit Tip and Ring [TTIP & TRING]. Analog line driver outputs. These pins connect via a 1:1.15
or 1:1.36 step-up transformer to the T1 line. See Section 14 for details.
Receive Analog Positive Supply [RVDD]. 5.0 volts ± 5%. Should be tied to the DVDD and TVDD pins.
Transmit Analog Positive Supply [TVDD]. 5.0 volts ± 5%. Should be tied to the RVDD and DVDD
pins.
Digital Signal Ground [DVSS]. Should be tied to the RVSS and TVSS pins.
Receive Analog Signal Ground [RVSS]. 0.0 volts. Should be tied to the DVSS and TVSS pins.
Transmit Analog Ground [TVSS]. 0.0 volts. Should be tied to the RVSS and DVSS pins.
SUPPLY PINS
Digital Positive Supply [DVDD]. 5.0 volts ± 5%. Should be tied to the RVDD and TVDD pins.
