CXA3256R

The CXA3256R is a type of 8-bit high-speed flash A/D converter which is capable of digitizing analog signals at the maximum rate of 120MSPS. ECL, PECL or TTL is able to be choosed as the digital input level in accordance with the application. The TTL digital output level accepts 1: 2 demultiplexed output. The CXA3256R is easier to be utilized by adding the new functions to the CXA3246Q and adopting a ultra-small package.

Features of the CXA3256R are:(1)Differential linearity error: ±0.5LSB or less; (2)Integral linearity error: .5LSB or les s; (3)High-speed operation with a maximum conversion rate of 120MSPS; (4)Low input capacitance: 10pF; (5)Wide analog input bandwidth: 250MHz; (6)Low power consumption: 500mW; (7)Power saving function; (8)1: 2 demultipl exed output; (9)1/2 frequency-divided clock output(with reset function); (10)Compatible with ECL, PECL and TTL digit al input levels.

The absolute maximum ratings of the CXA3256R can be summarized as:(1):supply voltage(AVCC, DVCC1, DVCC2)is0.5V to +7.0 V,supply voltage(DGND3)is0.5V to +7.0 V,supply voltage(DVEE3)is7.0 to +0.5 V;(2):analog input volt age(VIN) is VRT2.7 to AVCC V;(3):reference input voltage(VRT) is 2.7V to AVCC V;(4):digital input voltage(ECL/PECL input pin) is DVEE3 0.5 to DGND3 + 0.5 V; (5):storage temperature ranges from65 to +150 °C;(6):allowable po wer dissipation is 1.4 W.
