Available in two 16-pin small outline packages, it eliminates the need for an analog front end Si3018/19/10 (AFE), isolation transformer, relays, opto-isolators, and a 2- to 4-wire hybrid. The Si3056 dramatically reduces the number of discrete components and cost 1 16 DCT2 QE required to achieve compliance with global regulatory requirements. The Si3056 2 15 IGND DCT interfaces directly to standard modem DSPs. 3 14 DCT3 RX IB 4 13 QB Functional Block Diagram C1B 5 12 QE2 C2B 6 11 SC Si3056 Si3018/19/10 VREG 7 10 VREG2 8 9 RNG1 RNG2 MCLK RX SCLK IB FSYNC Digital SC SDI Interface US Patent 5,870,046 Hybrid and SDO dc DCT US Patent 6,061,009 FC/RGDT Termination VREG VREG2 Other Patents Pending Isolation Isolation DCT2 Interface Interface DCT3 RGDT/FSD/M1 RNG1 OFHK Control RNG2 M0 Interface Ring Detect QB Off-Hook RESET QE QE2 AOUT/INT Skyworks Solutions, Inc.
