Used to select which SCLK clock edge will update data at SDO
Signal Name:
SCLK
Signal Description:
Serial Port Clock
Signal Type:
Input
Used to clock data into and out of the serial port
5.1.6 LINE INTERFACE PINS
Signal Name:
MCLK
Signal Description:
Master Clock Input
Signal Type:
Input
A 2.048 MHz ( 0 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.
Signal Name:
RTIP & RRING
Signal Description:
Receive Tip and Ring
Signal Type:
Input
Analog inputs for clock recovery circuitry. These pins connect via a 1:1 transformer to the E1 line. See Section
19 for details.
Signal Name:
TTIP & TRING
Signal Description:
Transmit Tip and Ring
Signal Type:
Output
Analog line driver outputs. These pins connect via a 1:2 step–up transformer to the E1 line. See Section 19 for
details.
