STK10C68-K45I Datasheet
The AD8370 is a low cost, digitally controlled, variable gain amplifier that provides precision gain control, high IP3, and low noise figure. The excellent distortion performance and wide bandwidth make the AD8370 a suitable gain control device for modern receiver designs.

OUT can also be put into a low-current, pulse-skipping Coast Mode (13pA typical quiescent current) by reset- ting the RUN/COAST serial input bit. OUT supplies up t0 40mA in Coast Mode. Typically, when changing from Run to Coast Mode, a lower OUT voltage is also set (Table 4) to further reduce system operating current. The extent of this reduction depends on the minimum operating voltage of the system components when they are in standby or sleep states.

Symbol Name Description
CLK System Clock Active on the positive going edge to sample allinputs.
CS Chip Select Disables or Enables device operation by masking or enabling all inputs except CLK, CKE and L(U)DQM
CKE Clock Enable Masks system clock to freeze operation from the next clock cycle. CKE should be enabled at least one clock + tss prior to new command. Disable input buffers for power down in standby.
AOA12 Address Row / Column addresses are multiplexed on the same pins. Row address : RAO~RA12, Column address: CAO~CA8
BSO, BS1 Bank Select Address Selects bank to be activated during row address latch time. Selects band for read/write during column address latch time.
RAS Row Address Strobe Latches row addresses on the positive going edge of the CLK with RAS low. Enables row access & precharge.
CAS Column Address Strobe Latches column addresses on the positive going edge of the CLK with CAS low. Enables column access.
WE Write Enable Enables write operation and Row precharge.
L(U)DQM Data Input/Output Mask Makes data output Hi-Z, t SHZ after the clock and masks the output. Blocks data input when L(U)DQM active.
DQo.is Data Input/Output Data inputs/outputs are multiplexed on the same pins.
VDDNSS Power Supply/Ground Power Supply: +3.3V+0.3V/Ground
VDDQNSSQ Data Output Power/Ground Provide isolated Power/Ground to DQs for improved noise immunity.
NC/RFU No Connection


prty_en ln Enable parity checking on the Utopia interface. If disabled (tied t0 0), the wrx_err_stat(0) signal can be ignored and left open and the rx parity input should be tied t0 0. Also the tx parity pins can be left open.
cellsize[7:0] In Define cellsize: sets the size in bytes of a cell. Binary value to be set usually by board wiring.
