www.pericom.com | 1-408-232-9100 PI3EQX1204-B 3.3v, 12.5gbps 4 channel sas3/sata3/xaui redriver with pin strap and i 2 c control features pericom semiconductors PI3EQX1204-B is a sas3/sas2/ sata3/10ge, 4 differential channels redriver?. the device provides programmable equalization, output swing, pre-shoot, and de-emphasis by either pin strapping option or i2c control, to optimize performance over a variety of physical mediums by reducing inter-symbol interference. PI3EQX1204-B supports four 100-ohm differential cml data i/os and extends the signals across other distant data pathways on the users platform. the integrated equalization circuitry provides flexibility with signal integrity of the signal before the redriver, whereas the integrated de-emphasis and pre-shoot circuitry provides flexibility with signal integrity of the signal after the redriver. ? ? support up to 12.5gbps serial link for sas3, sas2, sata3, 10ge applications ? ? supporting 4 differential channels ? ? independent channel configuration of receiver equalization, output swing and pre-shoot/de-emphasis ? ? per channel activity detector with selectable input termination between 50 to v cc and 200k to v cc ? ? pin strap and i 2 c selectable device programming ? ? 3-bit selectable address bit for i 2 c ? ? supply voltage: 3.3v0.3v ? ? industrial temperature range: -40?c to 85?c ? ? packaging (pb-free & green): ? ? 42-contact tqfn (9mm x3.5mm) block diagram applications servers, storage + - + - er cm l o u t p u t am p lif ier i+ o + o - s elect ( 2 - b i t s) co n t r o l ( 4 - b i t s) m an ag e m en t bu f f r b u f f er co n t r o l ( 2 - b i t s) co n d i t io n al p u llu p , 50 - o h m , o r 2k - o h m u t + i+ + + - in p u t t h r esh o ld termination detect a m p d et ect b u f f er s elect ( 2 - b i t s) v o+ cc pre-sh swing delay delay buffer de-em de-emphasis output swing pre_shoot cml input vcc limiting equalizer power pen equalization conditional input power supply jbod up to 24 sas/sata drives raid controller lsi sas2x36 150mhz xo 150mhz xo pt7m6834 voltage mntr. supervisory ic pt7m6315 raid controller lsi sas2x36 sas drive sas drive pi3eqx12804 PI3EQX1204-B sas redriver 1.7v reset 4 4 4 4 2.9v pi3eqx12804 PI3EQX1204-B sas redriver application diagram product databrief new product brief
