IDT82V3011
T1/E1/OC3 WAN PLL WITH SINGLE REFERENCE INPUT
2
FUNCTIONAL DESCRIPTION
The IDT82V3011 is a T1/E1/OC3 WAN PLL with single reference
input, providing timing (clock) and synchronization (framing) signals to
interface circuits for multitrunk T1/E1 and STS3/OC3 links. The details
are described in the following sections.
2.1
STATE CONTROL CIRCUIT
The State Control Circuit is an important part in the IDT82V3011. It is
used to control the TIE block and the DPLL block as shown in Figure - 2.
The control is based on the result of Invalid Input Signal Detection and
the logic levels on the MODE_sel0, MODE_sel1 and TIE_en pins.
The IDT82V3011 can be operated in three different modes: Normal,
Holdover and Freerun. The operating mode is selected by the
MODE_sel1 and MODE_sel0 pins, as shown in Table - 1.
Figure - 3 shows the state control diagram. All state changes occur
synchronously on the rising edge of F8o. Three operating modes,
Normal (S1), Holdover (S3) and Freerun (S0) can be switched from one
to another by changing the logic levels on the MODE_sel0 and
MODE_sel1 pins.
