LOCKN

38

OD

Lock detect output (LOCKN).

It must be connected to Tx LOCKN with a Tx side10kΩ pull-up resistor. LOCKN is output only.

HTPDN

37

OD

Hot plug detect output (HTPDN).

It must be connected to Tx HTPDN with a Tx side 10kΩ pull-up resistor. HTPDN is output only.

Reserved [1,2]

It must be open.

Reserved [5]

8

-

It must be connected with a pull-up resistor to 3.3V.

DEOUT

9

O

DE signal output (DEOUT) for LVDS data sets.

When used as DEOUT, no external component is required. It is push pull output.

DEOUT output DE timing depending upon data stream state. DEOUT is output only.

Bit Error Test (BET) result output under Field-BET operation

H : No error, L : Bit error occured

DGLOCK

36

BPU

Multiple-chip configuration total Rx side LOCKN indicator (DGLOCK).

When used as DGLOCK, it is internally connected with a pull-up resistor to 3.3V. No external component is required.

LOCKN arrange among Rx Multiple-chip configuration is achieved by connecting all DGLOCK pins.
