Name/Description

Do Not Connect. Internal test point or reserved for future use.

Reference Voltage. Nominally –3.2 V. Can be used to bias LG1605DXB

(see data sheet). Load ≥10 kΩ.

Terminal for optional external capacitor to increase PLL damping (normally

not connected).

Terminal for external resistor to set PLL bandwidth (REQUIRED).

Loss of Signal Indicator. Provides approximately 1 mA sink current with

data signal present, can interface to CMOS, TTL when connected to logic

VDD through a 10 kΩ resistor. Normally grounded when not used.

Recovered Clock Out. ac couple or terminate into 50 Ω to GND.

Recovered Clock Out. ac couple or terminate into 50 Ω to GND.

Supply Voltage. –5.2 Vdc nominal.

Warning: Connecting a positive voltage to this pin will permanently

damage the device.

Regenerated Data Out. ac couple or terminate into 50 Ω to GND.

Regenerated Data Out. ac couple or terminate into 50 Ω to GND.

dc Feedback Voltage. Connect to V–TH.

Input Threshold Voltage. Connect to V–FB.

Negative Data Input. Internally ac coupled.

Positive Data Input. Internally ac coupled.

dc Feedback Voltage. Internally connected; not normally used.

No Internal Connection. May be grounded.

Ground. Connect to top ground plane of coplanar/microstrip circuit board.

GND

Ground. Does not need to be connected. GND pins provide all necessary

ground connections.
