The Si32260/1 devices operate from a 3.3V supply and have standard Si32260/1 6x8 mm PCM/SPI or GCI (8x8 mm package only) bus digital interfaces. A pair of built-in dc-dc converter controllers can be used to automatically generate 1 GPIO2A / SRINGCa 41 VDDA the optimal battery voltage required for each line-state, optimizing 2 GPIO1a / STIPCa 40 GPIO2b / SRINGCb SRINGDCa 3 39 GPIO1b / STIPCb efficiency and minimizing heat generation. 4 38 SRINGACa SRINGDCb HVPAD STIPACa 5 37 SRINGACb The Si32260/1 devices are designed to operate not only with a tracking STIPDCa 6 36 STIPACb CAPPa 7 35 STIPDCb battery supply for each channel for lowest power consumption, but also 8 CAPMa 34 IREF SVBATa 9 33 CAPPb with shared battery supplies, for lowest cost. When used with shared 10 32 SVDC CAPMb 11 RSTB 31 SVBATb GNDPAD battery supplies, the internal dc-dc controller operates in Tracking Shared INTB / DTXENB 12 30 SDI FSYNC 13 29 SDO Supply (TSS) mode to deliver power consumption lower than typical fixed 14 PCLK 28 SCLK DTX 15 27 CSB voltage shared rail designs (shared supplies are not currently supported 16 26 DRX VDDREG by the 6 x 8 mm package option). Self-testing and metallic loop testing (MLT) (e.g., GR-909) is facilitated by the built-in DSP, monitor ADC, and test load. The devices are available with linefeed voltage ratings of 110 V (Si32260) or 140 V (Si32261) to Patents pending support high voltage ringing, and both devices support wideband audio for better-than-PSTN voice quality. The Si32260/1 devices are available in a 6 x 8 mm 47-pin QFN package or an 8 x 8 mm 60-pin QFN package. Skyworks Solutions, Inc.
