Pin Description
Pin Number
Pin Name
Pin Function
1, 4
DIN, /DIN
Differential Data Inputs. If AC-coupled, terminate each pin to VREF with 50.
2
VREF
Reference Voltage Output. Typically VCC – 1.3V.
3, 11, 8
GND
Device Ground. Exposed pad must be soldered (or equivalent) to the same potential as the
ground pins.
10
/AUTO RESET
LVTTL Input. This pin is internally connected to a 25k pull-up resistor and defaults to HIGH.
When this pin is LOW or tied to ground, the /AUTO RESET function is enabled and SD deasserts
or LOS asserts within 120ns (typical) after the last high-to-low transition of the burst input. When
this pin is left floating or tied high, the AUTO RESET function is disabled and the SD deassert or
LOS assert must be forced by using the manual RESET function.
5, 16
VCC
Positive power supply. Bypass with 0.1uF | | 0.01uF low ESR capacitors. 0.01uF capacitors
should be as close as possible to VCC pins.
6
RESET
LVTTL Input. Apply a high-level signal (
>2V) to this pin to reset the SD deassert time or LOS
assert within 5ns. RESET defaults to LOW if left floating. If the /AUTO RESET function is not
used, this RESET function needs to be used to quickly deassert the SD or assert LOS. This pin
is internally connected to a 25k pull-down resistor and defaults to LOW.
