CXA3197R

CXA3197R 10-bit 125MSPS D/A Converter Description The CXA3197R is a high-speed D/A converter which can perform multiplexed input of two system 10-bit data. This IC realizes a maximum conversion rate of 125MSPS. Multiplexed operation is possible by inputing the 1/2 frequency-divided clock or by halving the frequency of the clock internally with the clock frequency divider circuit having the reset pin. The data input is at TTL level, and the clock input and reset input can select either TTL or PECL level according to the application. Features Maximum conversion rate: During PECL operation: 125MSPS During TTL operation: 100MSPS Resolution: 10 bits Low power consumption: 480mW (typ.) Data input level: TTL Clock, reset input level: TTL and PECL compatible 2:1 multiplexed input function 1/2 frequency-divided clock output possible by the built-in clock frequency divider circuit Voltage output (50Ω load drive possible) Single power supply or ±dual power supply operation Reset signal polarity switching function AGND2 AOUTP AOUTN 48 pin LQFP (Plastic) LEAD TREATMENT: PALLADIUM PLATING Structure Bipolar silicon monolithic IC Applications LCD DDS HDTV Communications (QPSK, QAM) Measuring devices 36 35 34 33 32 31 30 29 28 27 26 25 AGND2 37 VOCLP 38 R POLARITY 39 INV 40 PS 41 DVCC1 42 N.C. 43 DGND1 44 (MSB) DA9 45 DA8 46 DA7 47 DA6 48 1 2 3 4 5 6 7 8 9 10 11 12 24 RESETN/E 23 RESETP/E 22 RESET/T 21 CLKN/E 20 CLKP/E 19 CLK/T 18 DIV2OUT C1 DGND2 17 DIV2IN ...
