VCSO FEC PLL FOR SONET/OTN

P r e l i m i n a r y I n f o r m a t i o n

HS/PBO Operation

Optional Hitless Switching and Phase Build-out

Once triggered, the following HS/PBO sequence

occurs:

The M206x Series is available with a Hitless Switching

feature that is enabled during device manufacturing.

In addition, a Phase Build-out feature is also offered.

These features are offered as device options and are

specified by device order code. Refer to “Ordering

Information” on pg. 12.

1.The HS function disables the PLL Phase Detector

and puts the device into NBW (narrow bandwidth)

mode. The internal resistor Rin is changed to

2100kΩ . See Narrow Bandwidth (NBW) Control Pin

on pg. 6.

The Hitless Switching feature (with or without Phase

Build-out) is designed for applications where switching

occurs between two stable system reference clocks. It

should not be used in loop timing applications, or when

reference clock jitter is greater than 1 ns pk-pk. The

Hitless Switching sequence is triggered by the LOL

circuit, which is activated by a 4 ns phase transient. This

magnitude of phase transient can generated by the

CDR (Clock & Data Recovery unit) in loop timing mode,

especially during a system jitter tolerance test. It can

also be generated by some types of Stratum clock

DPLLs (digital PLL), especially those that do not include

a post de-jitter APLL (analog PLL).

2.If included, the PBO function adds to (builds out) the

phase in the clock feedback path (in VCSO clock

cycle increments) to align the feedback clock with

the (new) reference clock input phase.

3.The PLL Phase Detector is enabled, allowing the

PLL to re-lock.

4.Once the PLL Phase Detector feedback and input

clocks are locked to within 2 nsec for 8 consecutive

cycles, a timer (WBW timer) for resuming wide

bandwidth (in 175 nsec) is started.

5.When the WBW timer times out, the device reverts

to wide loop bandwidth mode (i.e., Rin is returned to

100kΩ) and the HS/PBO function is re-armed.

The LOL pin will indicate lock status on a cycle-to-cycle

basis and may be intermittent until PLL phase lock has

fully stabilized.

When the M206x Series is operating in wide bandwidth

mode (NBW=0), the optional Hitless Switching function

puts the device into narrow bandwidth mode during the

Hitless Switching sequence. This allows the PLL to lock

the new input clock phase gradually. With proper

configuration of the external loop filter, the output clock

phase change complies with MTIE and TDEV

specifications for GR-253 (SONET) and ITU G.813

(SDH) during input reference clock changes.

The optional proprietary Phase Build-out (PBO)

function enables the PLL to absorb most of the phase

change of the input clock during reference switching.

The PBO function selects a new VCSO clock edge for

the PLL Phase Detector feedback clock, selecting the

edge closest in phase to the new input clock phase.

This reduces re-lock time, the generation of wander,

and extra output clock cycles.

The Hitless Switching and Phase Build-out functions

are triggered by the LOL circuit. For proper operation,

a low phase detector frequency must be avoided. See

“Guidelines for Using LOL” on pg. 6 for information

regarding the phase detector frequency.

HS/PBO Sequence Trigger Mechanism

The HS function (or the combined HS/PBO function)

is armed after the device locks to the input clock refer-

ence. Once armed, HS is triggered by the occurance of

a Loss of Lock condition. This would typically occur as a

consequence of a clock reference failure, a clock failure

upstream to the M206x Series, or a M206x Series clock

reference mux reselection.
