Integrated Cross Point s witches activate the input selected by the user. In single channel mode, one of the four inputs can be selected as a 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, 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 operational modes. t he HMCAD1511 is based on a proprietary structure, and employs internal reference circuitry, a serial control interface and serial Lv Ds /rs Ds output data. Data and frame synchronization clocks are supplied for data capture at the receiver. Internal 1 to 50X digital coarse gain with eno B > 7.5 up to 16X gain, allows digital implementation of oscilloscope gain settings. 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 data format can be selected through this interface. A full chip idle 0 mode can be set by a single external pin. r egister settings determine the exact function of this pin. HMCAD1511 is designed to easily interface with Field Programmable Gate Arrays (FPGAs) from several vendors. electrical Specifications dC Specifications Av DD = 1.8v, Dv DD = 1.8v, ov DD = 1.8v, Fs = 125 Ms Ps , Quad Channel Mode, 50% clock duty cycle, -1 dBFs 70 MHz input signal, 1x/0 dB digital gain (fine and coarse), unless otherwise not ed Parameter Description Min Typ Max Unit DC accuracy n o missing codes Guaranteed o ffset o ffset error after internal digital offset correction 0.05 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 0.5 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 For price, delivery, and to place orders: Analog Devices, Inc., One Technology Way, P.O.
