TURBOCLOCK™

IDT5993A

FEATURES:

DESCRIPTION:

• 3 pairs of programmable skew outputs

• Low skew: 200ps same pair, 250ps all outputs

• Selectable positive or negative edge synchronization:

Excellent for DSP applications

• Synchronous output enable

• Output frequency: 3.75MHz to 100MHz

• 2x, 4x, 1/2, and 1/4 outputs

The IDT5993A is a high fanout PLL based clock driver intended for

high performance computing and data-communications applications. A

key feature of the programmable skew is the ability of outputs to lead or

lag the REF input signal. The IDT5993A has six programmable skew

outputs and two zero skew outputs. Skew is controlled by 3-level input

signals that may be hard-wired to appropriate HIGH-MID-LOW levels.

• 5V with TTL outputs

• 3 skew grades:

IDT5993A-2: tSKEW0<250ps

IDT5993A-5: tSKEW0<500ps

IDT5993A-7: tSKEW0<750ps

• 3-level inputs for skew and PLL range control

• PLL bypass for DC testing

• External feedback, internal loop filter

• 46mA IOL high drive outputs

• Low Jitter: <200ps peak-to-peak

• Outputs drive 50Ω terminated lines

• Available in QSOP package
