Hot-selling and scarce DAC34SH84IZAYR Quad-Channel, 16-Bit, 1.5 GSPS Digital-to-Analog Converter NFBGA19 spot stock

Product Descriptions

The DAC34SH84 is a very low-power, high-dynamicrange,      quad-channel,      16-bit      digital-to-analogconverter  (DAC)  with  a  sample  rate  as  high  as1.5 GSPS .

The device includes features that simplify the designof complex transmit architectures: 2 × to  16 × digitalinterpolation  filters  with  over  90  dB  of  stop-bandattenuation     simplify    the     data     interface     andreconstruction  filters .  Independent  complex  mixersallow flexible carrier placement . A high-performancelow-jitter  clock  multiplier  simplifies  clocking  of  thedevice  without  significant  impact  on  the  dynamicrange .  The  digital  quadrature  modulator  correction(QMC) enables complete  IQ compensation for gain,offset   and   phase   between   channels   in   directupconversion applications .

Digital  data  is  input to the  device through  a  32-bitwide  LVDS  data  bus with  on-chip termination . Thewide  bus  allows  the  processing  of  high-bandwidthsignals .  The  device  includes  a  FIFO,  data  patternchecker, and parity test to ease the input interface .The   interface  also  allows  full  synchronization  ofmultiple devices .

The  device  is  characterized  for  operation  over  theentire industrial temperature range of –40°C to 85°Cand is available in a 196-ball, 12-mm × 12-mm, 0.8-mm pitch BGA package .

The DAC34SH84 low-power, high-bandwidth support,superior crosstalk, high dynamic range, and featuresare  an  ideal  fit  for  next-generation  communicationsystems .
