ICS8501

The ICS8501 is a low skew, 1-to-16 differential current mode fanout buffer and a member of the HiPerCIockSTM family of high performance clock solutions from ICS. The ICS8501 is designed to translate any differential signal levels small swing differential current mode(DCM) output levels. external reference resistor is used to set the value ofthe current supplied to an external load load/termination resisor. The load resistor value is chosen to equal the value of The characteristic line impedance of 5052. The ICS8501 is characterized at an operating supply voltage of 3.3V. The small swing outputs, accurate crossover voltage and duty cycle makes the ICS8501 ideal for interfacing to today's most advanced microprocessors.

The features of ICS8501 can be summarized as (1)16 small swing DCM outputs; (2)translates any differential input signal(PECL, HSTL, LVDS, DCM) to DCM levels without external bias networks; (3)translates single ended input levels to DCM levels with a resistor bias network on the CLK input; (4)translates single ended input levels to inverted DCM levels with a resistor bias network on the CLK input; (5)Voh(max) = 1.2V; (6)40% of Voh Vcrossover60% of Voh; (7)45% duty cycle 55%; (8)output frequency up to 500MHz; (9)100ps output skew; (10)3.3V operating supply; (11)48 lead low-profile QFP(LQFP), 7mm x 7mm x 1.4mm package body, 0.5mm package lead pitch; (12)0°C to 70°C ambient operating temperature.

The absolute maximum ratings of ICS8501 are (1)supply voltage: 4.6V; (2)inputs: -0.5V to VCC +0.5V; (3)ambient operating temperature: 0°C to +70°C; (4)storage temperature: -65°C to +150°C; (5)output: -0.5V to VCC+0.5V (stresses above those listed Lmder absolute maximum ratings may cause permanent damage to the device. These ratings are stress specifications only and functional operation of the device at these or any other conditions above those listed in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability).
