DS1 Receive Interfaces

Pin #

Name I/O/P

Description

62

CR1

O Receive Clock Channels 1 - 28. TTL Type III compatible. Receive data is

43

CR2

clocked out of the MT90737 on positive transitions. The clock for the first DS1

41

CR3

channel corresponds to CR1, while the clock for the last DS1 channel corre-

39

CR4

sponds to CR28. The DS1 clock signals are derived from the DS3 clock signal

37

CR5

(DS3CR). During periods of DS3/DS2 out of frame or AIS, the MT90737 pro-

35

CR6

vides a DS1 clock signal for clocking out AIS which is derived from the XCK

33

CR7

clock (pin 90).
