Integrated Cross Point s witches activate the input selected by the user. In s ingle Channel Mode, one of the four inputs can be selected as valid input to the single ADC channel. In Dual Channel Mode, any two of the four inputs can be selected to each ADC channel. In Quad Channel Mode and Precision Mode, any input can be assigned to any ADC channel. An internal, low jitter and programmable clock divider makes it possible to use a single clock source for all opera- tional modes. t he HMCAD1520 is based on a proprietary structure, and employs internal reference circuitry, a serial control inter- face and a serial Lv Ds output data. Data and frame synchronization clocks are supplied for data capture at the receiver. Internal digital fine gain can be set separately for each ADC to calibrate for gain errors. various modes and configuration settings can be applied to the ADC through the serial control interface ( s PI). each channel can be powered down independently and output data format can be selected through this interface. A full chip 0 idle mode can be set by a single external pin. r egister settings determine the exact function of this pin. HMCAD1520 is designed to interface easily with Field Programmable Gate Arrays (FPGAs) from several vendors. electrical Specifications dC Specifications Av DD = Dv DD = ov DD = 1.8v, F = 160 Ms Ps , Quad Channel 12-bit High s peed Mode, 50% Clock Duty Cycle, s -1 dBFs 70 MHz Input s ignal, 1x / 0 dB Digital Gain (Fine and Coarse), Unless o therwise n oted Parameter Description Min Typ Max Unit DC accuracy n o missing codes Guaranteed o ffset o ffset error after internal digital offset correction 1 Ls B G Gain error 6 %Fs abs Gain matching between channels. 3 sigma value at worst G 0.5 %Fs rel case conditions Dn L Differential non linearity 0.2 Ls B In L Integral non linearity 0.6 Ls B v Common mode voltage output v /2 CM,out Av DD Analog Input v Analog input common mode voltage v -0.1 v +0.2 v CM,in CM CM Fsr Differential input voltage full scale range 2 v pp C Differential input capacitance, Quad channel mode 5 pF in,Q C Differential input capacitance, Dual channel mode 7 pF in,D C Differential input capacitance, s ingle channel mode 11 pF in,s Power Supply v Analog s upply voltage 1.7 1.8 2 v Av DD v Digital and output driver supply voltage 1.7 1.8 2 v Dv DD v Digital CMos Input s upply voltage 1.7 1.8 3.6 v ov DD Temperature t o perating free-air temperature -40 85 C A Information furnished by Analog Devices is believed to be accurate and reliable.
