Technical Specifications
Technical Summary
This QUANTA COMPUTER VM8G modem board, dated Tuesday, March 10, 2009, is built around the CX20548-S modem IC in an MLF2_16P_0-65_4-0X4-0 package. The board includes multiple RJ11 connectors (MJ1, MJ3, MJ5, MJ4) and a FI-S2P-HF connector (MJ2). Key passive components include high-voltage capacitors such as MC9 (470P/3KV/1808) and MC8 (470P/3KV/1808), along with ferrite beads (MFB2, MFB1) rated at 300A/0.3A. The design incorporates MMBTA42 transistors (MQ1, MQ3, MQ4, MQ2) and MMBD3004S diodes (MBR2, MBR1). A TB3100M TVS diode (MRV1) is used for surge protection. The board also features a HALL Sensor reference and specific layout notes regarding MRa and MCa placement near the RXI pin.
