Datasheet

1:12 LVDS Output 1.8V Fanout Buffer

Description

Features

The IDT8P34S1212I is a high-performance differential LVDS fanout

buffer. The device is designed for the fanout of high-frequency, very

low additive phase-noise clock and data signals. The

IDT8P34S1212I is characterized to operate from a 1.8V power

supply. Guaranteed output-to-output and part-to-part skew

characteristics make the IDT8P34S1212I ideal for those clock

distribution applications that demand well-defined performance and

repeatability.

• 12 low skew, low additive jitter LVDS output pairs

• Two selectable, differential clock input pairs

• Differential CLK0, CLK1 pairs can accept the following differential

input levels: LVDS, CML

• Maximum input clock frequency: 1.2GHz (maximum)

• LVCMOS/LVTTL interface levels for the control input select pin

• Output skew: 10ps (typical)

Two selectable differential inputs and 12 low skew outputs are

available. The integrated bias voltage reference enables easy

interfacing of single-ended signals to the device inputs. The device is

optimized for low power consumption and low additive phase noise.

• Propagation delay: 340ps (typical)

• Low additive phase jitter, RMS; f_REF= 156.25MHz, V_PP= 1V,

12kHz- 20MHz: 41fs (typical)

• Maximum device current consumption (I_DD): 227mA (maximum)

at 1.89V

• Full 1.8V supply voltage

• Lead-free (RoHS 6), 40-Lead VFQFN packaging

• -40°C to 85°C ambient operating temperature
