Transmit Clock (TXCLK) Receive Clock (RXCLK)
Transmit Clock (TXCLK) Receive Clock (RXCLK) pins used synchronous (sync) mode serial communication. They needed when using synchronous terminal device keep synchronization between modem terminal device serial port. Transmit Clock (TXCLK) Receive Clock (RXCLK) used asynchronous mode. However, most applications asynchronous mode because synchronous ports common asynchronous ports computer hardware. asynchronous operation host system does need connect TXCLK RXCLK pins RJModem; 9-pin interface. Synchronous mode with command stored with command. RJModem command guide available RJModem Developer Multi-Tech site.

Design Considerations
Good engineering practices must adhered when designing printed circuit board (PCB) containing RJModem. Suppression noise essential proper operation performance modem itself surrounding equipment. aspects noise board design containing Modem must considered: on-board/off-board generated noise that affect digital signal processing. Both on-board off-board generated noise that coupled on-board affect interface signal levels quality. particular concern noise frequency ranges affecting modem performance. On-board generated electromagnetic interference (EMI) noise that radiated conducted off-board separate, equally important, concern. This type noise affect operation surrounding equipment. Most local government agencies have stringent certification requirements that must specific environments. Proper board layout (component placement, signal routing, trace thickness geometry, etc.) component selection (composition, value, tolerance), interface connections, shielding required board design achieve desired modem performance attain certification. aspects proper engineering practices beyond scope this designer guide. designer should consult noise suppression techniques described technical publications journals, electronics electrical engineering text books, component supplier application notes.
Board Layout Guidelines
4-layer design, provide adequate ground plane covering entire board. 4-layer designs, power ground typically inner layers. power ground traces should 0.05 inches wide. recommended hole size Modem pins 0.036 +/-0.003 (check with this) diameter. creepages clearances RJModem have been designed meet requirements safety standards EN60950. requirements based working voltage 250V.
Electromagnetic Interference (EMI) Considerations
following guidelines offered specifically help minimize generation. Some these guidelines same similar general guidelines mentioned again reinforce their importance. order minimize contribution RJModem design, designer must understand major sources reduce them acceptable levels.
Keep traces carrying high frequency signals short possible. Provide good ground plane grid. some cases, multilayer board required with full layers
ground power distribution. Decouple power from ground with decoupling capacitors close RJModem module power pins possible. Eliminate ground loops, which unexpected current return paths power source ground. Decouple power cord power cord interface with decoupling capacitors. Methods decouple power lines similar decoupling telephone lines. Locate high frequency circuits separate area minimize capacitive coupling other circuits. Locate cables connectors avoid coupling from high frequency circuits. highest frequency signal traces next ground grid. multilayer board design used, make cuts ground power planes sure ground plane covers traces. Minimize number through-hole connections traces carrying high frequency signals. Avoid right angle turns high frequency traces. Forty-five degree corners good; however, radius turns better. 2-layer boards with ground grid, provide shadow ground trace opposite side board traces carrying high frequency signals. This will effective high frequency ground return three times width signal traces. Distribute high frequency signals continuously single trace rather than several traces radiating from point.
