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 CDK1308 Ultra Low Power, 20/40/65/80MSPS, 10-bit Analog-to-Digital Converters (ADCs) CDK1308 Ultra Low Power, 20/40/65/80MSPS, 10-bit ADCs FEATURES n n n General Description The CDK1308 is a high performance ultra low power analog-to-digital converter (ADC). The ADC employs internal reference circuitry, a CMOS control interface and CMOS output data, and is based on a proprietary structure. Digital error correction is employed to ensure no missing codes in the complete full scale range. Two idle modes with fast startup times exist. The entire chip can either be put in Standby Mode or Power Down mode. The two modes are optimized to allow the user to select the mode resulting in the smallest possible energy consumption during idle mode and startup. The CDK1308 has a highly linear THA optimized for frequencies up to Nyquist. The differential clock interface is optimized for low jitter clock sources and supports LVDS, LVPECL, sine wave, and CMOS clock inputs. 10-bit resolution 20/40/65/80MSPS max sampling rate Ultra-Low Power Dissipation: 15/25/38/46mW 61.6dB SNR at 80MSPS and 8MHz FIN Internal reference circuitry 1.8V core supply voltage 1.7 – 3.6V I/O supply voltage Parallel CMOS output 40-pin QFN package Pin compatible with CDK1307 n n n n n n n APPLICATIONS n n n n n n Medical Imaging Portable Test Equipment Digital Oscilloscopes IF Communication Video Conferencing Video Distribution Functional Block Diagram Rev 1A 10 Ordering Information Part Number CDK1308AILP40 CDK1308BILP40 CDK1308CILP40 CDK1308DILP40 Speed 20MSPS 40MSPS 65MSPS 80MSPS Package QFN-40 QFN-40 QFN-40 QFN-40 Pb-Free Yes Yes Yes Yes RoHS Compliant Yes Yes Yes Yes Operating Temperature Range -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C Packaging Method Tray Tray Tray Tray Moisture sensitivity level for all parts is MSL-2A. ©2009 CADEKA Microcircuits LLC www.cadeka.com Data Sheet Pin Configuration CM_EXTBC_0 CM_EXTBC_1 QFN-40 SLP_N OVDD OVDD D_9 D_8 D_7 D_6 D_5 CDK1308 Ultra Low Power, 20/40/65/80MSPS, 10-bit ADCs 40 39 38 37 36 35 34 33 32 DVDD CM_EXT AVDD AVDD IP IN AVDD DVDDCLK CLKP CLKN 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 31 30 29 28 D_4 D_3 D_2 CLK_EXT OVDD OVDD ORNG D_1 D_0 NC CDK1308 QFN-40 27 26 25 24 23 22 21 DFRMT OE_N OVDD OVDD NC DVDD Pin Assignments Pin No. 0 1, 11, 16 2 3, 4, 7 5, 6 8 9 10 12 13 14 15 17, 18, 25, 26, 36, 37 19 20 21 22 Pin Name VSS DVDD CM_EXT AVDD IP, IN DVDDCLK CLKP CLKN CLK_EXT_EN DFRMT PD_N OE_N OVDD NC NC NC D_0 Output Data (LSB) Description Ground connection for all power domains.
