designed primarily for Clock or Data de−skewing and timing
adjustment. The NB6L295 is versatile in that two individual variable
delay channels, PD0 and PD1, can be configured in one of two

operating modes, a Dual Delay or an Extended Delay.

In the Dual Delay Mode, each channel has a programmable delay
section which is designed using a matrix of gates and a chain of
multiplexers. There is a fixed minimum delay of 3.2 ns per channel.

The Extended Delay Mode amounts to the additive delay of PD0
plus PD1 and is accomplished with the Serial Data Interface MSEL bit
set High. This will internally cascade the output of PD0 into the input
of PD1. Therefore, the Extended Delay path starts at the IN0/IN0

6 ns per channel in Dual Delay Mode; or from 0 ns to 11.2 ns for the
Extended Delay Mode.
The Multi−Level Inputs can be driven directly by differential
LVPECL, LVDS or CML logic levels; or by single ended LVPECL,
LVCMOS or LVTTL. A single enable pin is available to control both
inputs. The SDI input pins are controlled by LVCMOS or LVTTL
level signals. The NB6L295 LVPECL output contains temperature
compensation circuitry. This device is offered in a 4 mm x 4 mm
24−pin QFN Pb−free package. The NB6L295 is a member of the
ECLinPS MAX™ family of high performance products.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
5. LVPECL outputs loaded with 50 W to VCC − 2.0 V for proper operation.
6. Input and output parameters vary 1:1 with VCC.
7. Vth, VIH, VIL,, and VISE parameters must be complied with simultaneously. Vth is applied to the complementary input when operating in
single−ended mode.
8. VIHD, VILD, VID and VCMR parameters must be complied with simultaneously.
9. VCMR(min) varies 1:1 with voltage on GND Pin, VCMR(max) varies 1:1 with VCC. The VCMR range is referenced to the most positive side
of the differential input signal.
