LTCKn: Line Transmit Clock for Framer 1 ~ 8
It is a nominal E1 (2.048MHz) or T1/J1 (1.544MHz) clock. LTCK can be derived from TSCCKA, TSCCKB, LRCK or
XCK. On the active edge of LTCKn, the corresponding LTDn is updated.
XCK: Crystal Clock
The clock frequency equals 49.152MHz ± 50 ppm 50% duty cycle for E1 and 37.056MHz ± 32 ppm 50% duty cycle
for T1/J1.
RST: Reset (Active Low)
A low signal for at least 100 ns on this pin will reset the device anytime. RST is a Schmitt-trigger input with weak
pull-up.
This pin must be asserted low to enable the microprocessor interface. The signal must be asserted high at least
once after power up to clear the internal test modes. A transition from high to low must occur on this pin for each
Read/Write operation and can not return to high until the operation is over.
INT: Open-Drain Interrupt Signal (Active Low)
This pin will keep low until all the active unmasked interrupt are acknowledged at their sources.
A[10:0]: Address Bus
The signals on these pins select the register for the microprocessor to access.
D[7:0]: Bi-directional Data Bus
Signals on these pins are the data for Read/Write operation.
A low signal on this pin enables a read operation on the selected register.
A low signal on this pin enables a write operation on the selected register.
ALE: Address Latch Enable
In non-multiplexed address/data bus, the ALE is connected to High.
It is internally pulled-up.
Microprocessor Interface
JTAG (per IEEE 1149.1)
