LVDS Programmable Delay Line
8S89296
Datasheet
Description
The 8S89296 is a high performance LVDS programmable delay line.
The delay can vary from 2.2ns to 12.5ns in 10ps steps. The 8S89296
is characterized to operate from a 2.5V power supply and is
guaranteed over industrial temperature range.
The delay of the device varies in discrete steps based on a control
word. A 10-bit long control word sets the delay in 10ps increments.
Also, the input pins IN and nIN default to an equivalent low state
when left floating. The control register can accept CMOS or TTL
level signals.

Parallel data input D9.
Single-ended LVCMOS, LVTTL, LVPECL interface levels.
Parallel data input D10.
Single-ended LVCMOS, LVTTL, LVPECL interface levels.
Non-inverting differential input.
Inverting differential input.
Reference voltage output. This pin can be used to re-bias AC-coupled inputs to IN
and nIN. When used, de-couple to VDD using a 0.01F capacitor. If not used, leave
floating.
Reference voltage output. See Table 4.
Reference voltage input. The voltage driven on VCF sets the logic transition
threshold for D[10:0].
Power supply ground.
D inputs LOAD and HOLD control input. When HIGH, latches the D[10:0] bits. When
LOW, the D[10:0] latches are transparent. Single-ended LVPECL interface levels.
See Table 3.
