Data Sheet A m p l i fy t h e H u m a n E x p e r i e n c e CDK1301 8-bit, 250 MSPS A/D Converter www.datasheet4u.com with Demuxed Outputs features n n n n n n n CDK1301 8-bit, 250 MSPS A/D Converter with Demuxed Outputs General Description The CDK1301 is a high-speed, 8-bit analog-to-digital converter implemented in an advanced BiCMOS process. It is a performance-enhanced version of the CDK1300, offering better linearity and dynamic performance. An advanced folding and interpolating architecture provides both a high conversion rate and very low power dissipation of only 425mW. The analog inputs can be operated in either single-ended or differential input mode. A 2.5V common mode reference is provided on chip for the single-ended input mode to minimize external components. The CDK1301 digital outputs are demuxed (double-wide) with both dualchannel and single-channel selectable output modes. Demuxed mode supports either parallel aligned or interleaved data output. The output logic is both +3.0V and +5.0V compatible. The CDK1301 is available in a 44-lead TQFP surface mount package over the industrial temperature range of -40°C to +85°C. TTL/CMOS/PECL input logic compatible High conversion rate: 250 MSPS Single +5V power supply Very low power dissipation: 425mW 350MHz full power bandwidth Power-down mode: 24mW +3.0V/+5.0V (LVCMOS) digital output Single/demuxed output ports selectable Improved replacement for AD9054 logic compatibility n n Applications n n n n n RGB video processing Digital communications High-speed instrumentation Digital Sampling Oscilloscopes (DSO) Projection display systems Block Diagram REV 1A Ordering Information Part Number CDK1301ITQ44 CDK1301ITQ44_Q Package TQFP-44 TQFP-44 Pb-Free Yes No RoHS Compliant Yes No Operating Temperature Range -40°C to +85°C -40°C to +85°C Packaging Method Rail Rail Moisture sensitivity level for all parts is MSL-1. ©2008 CADEKA Microcircuits LLC www.cadeka.com Data Sheet Pin Configuration TQFP-44 CDK1301 8-bit, 250 MSPS A/D Converter with Demuxed Outputs www.datasheet4u.com CDK1301 Pin Assignments Pin No. 40 39 16-9 19-26 28 27 4 3 5 6 Pin Name VIN+ VINDA0–DA7 DB0–DB7 DCLKOUT DCLKOUT CLK CLK RESET RESET Description Non-inverted analog input; nominally 1Vpp; 100k pullup to Vcc and 100k pulldown to AGND, internally Inverted analog input; nominally 1Vpp; 100k pullup to Vcc and 100k pulldown to AGND, internally Data output bank A; 3V/5V LVCMOS compatible Data output bank B; 3V/5V LVCMOS compatible Non-inverted data output clock; 3v/5v 3V/5V LVCMOS compatible Inverted data output clock; 3V/5V LVCMOS compatible Non-inverted clock input pin; 100k pulldown to AGND, internally Inverted clock input pin; 17.5k pullup to Vcc and 7.5k pulldown to AGND, internally RESET synchronizes the data sampling and data output bank relationship when in dual channel mode (DMODE1 = 0); 100k pulldown to AGND, internally Inverted RESET input pin; 17.5k pullup to Vcc and 7.5 pulldown to AGND, internally Internally: 100k pulldown to AGND on DMODE1 50k pullup to Vcc on DMODE2 32, 31 DMODE1,2 Data output mode pins: DMODE1 = 0, DMODE2 = 0: parallel dual channel output DMODE1 = 0, DMODE2 = 1: interleaved dual channel output DMODE1 = 1, DMODE2 = x: single channel data output on bank a (125 MSPS max) 2 37 35, 36, 42, 43 7, 17, 30 1, 33, 34, 38, 41, 44 8, 18, 29 PD VCM AVCC OVDD AGND DGND Power-Down pin; PD = 1 for Power-Down mode.
