CXA3246Q

CXA3246Q 8-bit 120MSPS Flash A/D Converter Description The CXA3246Q is an 8-bit high-speed flash A/D converter capable of digitizing analog signals at the maximum rate of 120MSPS. ECL, PECL or TTL can be selected as the digital input level in accordance with the application. The TTL digital output level allows 1: 2 demultiplexed output. Features Differential linearity error: ±0.5LSB or less Integral linearity error: ±0.5LSB or less High-speed operation with a maximum conversion rate of 120MSPS Low input capacitance: 10pF Wide analog input bandwidth: 250MHz Low power consumption: 500mW 1: 2 demultiplexed output 1/2 frequency-divided clock output (with reset function) Compatible with ECL, PECL and TTL digital input levels TTL output "H" levels: 2.8V (Typ.) +3.3V line CMOS IC direct connecting available Single +5V power supply operation available Surface mounting package (48-pin QFP) Pin Configuration (Top View) DGND3 AVCC VRB DVEE3 1 48 RESETN/E 47 RESET/E 46 RESETN/T 45 SELECT 44 INV 43 CLKOUT 42 DVCC2 41 DGND2 40 PBD7 39 PBD6 38 PBD5 37 PBD4 25 26 27 28 29 30 31 32 33 34 35 36 48 pin QFP (Plastic) LEAD TREATMENT: PALLADIUM PLATING Structure Bipolar silicon monolithic IC Applications Magnetic recording (PRML) Communications (QPSK, QAM) LCDs Digital oscilloscopes AGND 12 11 10 CLK/E 13 CLKN/E 14 CLK/T 15 N.C. 16 N.C. 17 N.C. 18 DVCC2 19 DGND2 20 PAD0 21 PAD1 22 PAD2 23 PAD3 24 9 8 7 6 5 4 AGND 3 AVCC VRM3 VRM2 VRT VRM1 VIN 2 ...
