8 / 12 page PULSEJACKTM Surface Mount 1x1 J0C Application Note This line of 10/100Base-TX SMT RJ45 1X1 Connector Magnetics Modules has been specifically designed for the implementation of a 10Base-T and 100Base-TX transmission over data-grade unshielded twisted pair cable (UTP-3, 5e and 6). The connectors provide excellent EMI filtering and are suitable for adapter card and multiport applications. Pulse has worked closely with the leading IC manufacturers in providing these 10/100 solutions, thereby assuring compatibility with each transceiver. The JC0 series meets the stringent open circuit inductance requirements imposed by IEEE. When an 8mA DC current is applied across the transformer windings, the transformer will provide at least 350µH. The transformers used in each module also provide 1500Vrms minimum isolation, wide bandwidth with minimal attenuation and fast rise times to minimize system level jitter. The 1X1 SMT RJ45 connectors manufactured by Pulse are designed to meet all published specifications after exposure to surface mount soldering temperatures. The SMT are robust enough to withstand convection and infrared reflow solder temperatures. Additionally, compliant leads provide excellent solder-joint reliability with a coplanarity of 0.10mm (0.004") NOTE: Modules are packaged in trays, unless Tape & Reel is specified. Please add the suffix "T" for Tape & Reel orders (ex: J0C-0003T). Add the suffix “NL” for RoHS compliant parts (ex: J0C-0003NL for Trays and J0C-0003NLT for Tape & Reel). PCB Layout Recommendations: 1. For maximum EMI suppression (electromagnetic interference) place the decoupling capacitors adjacent to Vcc and 50 Ω connections. 2. Connections to ground should be as short as possible. 3. Connections between the 10/100 IC and the SMT connector should be direct (ideally no change in direction) and of minimum length. 8 7 6 5 4 3 2 1 6 5 4 3 2 1 TX 1:1 RJ45 RX 1:1 J0C-003/4 Connector VCC TPOR - TPOR + TPIP + NC RX+ TX- TX+ TXCT RX- 0.01 µf 50W * 2 0.01 µf 0.01 µf Shield PCB PAD Shield PCB PAD TPOP - 10/100 IC PHY 0.01 µf 50W * 2 Chassis GND Analog GND NOTE: Connector design not to scale 8 7 NC NC www.pulseeng.com 8 J409.G (12/07) USA 858 674 8100 •• Germany 49 7032 7806 0 •• Singapore 65 6287 8998 •• Shanghai 86 21 54643211/2 •• China 86 769 85538070 •• Taiwan 886 3 4641811 |
