IDT5T9950/A 2.5V PROGRAMMABLE SKEW PLL CLOCK DRIVER TURBOCLOCK II JR. INDUSTRIAL TEMPERATURE RANGE 2.5V PROGRAMMABLE SKEW PLL CLOCK DRIVER TURBOCLOCK™ II JR. IDT5T9950/A FEATURES: DESCRIPTION: • • • • The IDT5T9950 is a high fanout 2.5V 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 IDT5T9950 has eight programmable skew outputs in four banks of 2. Skew is controlled by 3-level input signals that may be hard-wired to appropriate high-mid-low levels. When the sOE pin is held low, all the outputs are synchronously enabled. However, if sOE is held high, all the outputs except 2Q0 and 2Q1 are synchronously disabled. The LOCK output asserts to indicate when Phase Lock has been achieved. Furthermore, when PE is held high, all the outputs are synchronized with the positive edge of the REF clock input. When PE is held low, all the outputs are synchronized with the negative edge of REF. The IDT5T9950 has LVTTL outputs with 12mA balanced drive outputs. Ref input is 3.3V tolerant 4 pairs of programmable skew outputs Low skew: 185ps same pair, 250ps all outputs Selectable positive or negative edge synchronization: Excellent for DSP applications Synchronous output enable Input frequency: – Std: 6MHz to 160MHz – A: 6MHz to 200MHz Output frequency: – Std: 6MHz to 160MHz – A: 6MHz to 200MHz 2x, 4x, 1/2, and 1/4 outputs 3-level inputs for skew and PLL range control PLL bypass for DC testing External feedback, internal loop filter 12mA balanced drive outputs Low Jitter:
