TuneCodes above 250 are reserved for special operations. Power save mode shuts off all PIN diodes for lowest power consumption.

PARALLEL MODE In parallel mode, the TuneCode is specified per the input pins when the /STB line goes low. Once strobed, an internal processor looks up the required PIN diode control words and sets them accordingly. The PIN diode switch drivers take another ten microseconds to slew on or off, and the resulting bandpass is indeterminate during this time.

Figure 3: Parallel Mode Timing SERIAL (SPI) MODE The TuneCode is clocked in serially one bit at a time, MSB first. Timing is synchronous and can be at any rate under the maximum clock rate of 5MHz. To start a sequence, the chip select line (/SS) is pulled low. Once /SS goes high, the internal processor begins the decoding process and sets the new frequency.

Figure 4: Serial Mode Timing RS-232 (ASYNC) MODE The baud rate is fixed at 9600, 8N1. Voltage levels are TTL, with mark high, space low. Be careful not to use TuneCodes 253 and 254 as they are reserved for manufacturing and calibration purposes. Use of these codes may cause indeterminate results.

APPLICATION INFORMATION The power handling capability of the filter is dependent on VSWR, bandwidth, and bias voltage. Lower levels of bias voltage, all the way down to +10V are possible, as long as RF signal levels remain appropriately low. Power levels should be reduced to below 0dBm during switching.

Figure 7: Power Handling versus Bias and Bandwidth SOLDERING The TS-5010 should be hand soldered. Wave solder or IR reflow may cause parts on the internal circuit boards to loosen or shift position. The use of sockets is acceptable. NC PINS Do not connect anything to the NC (no connect) pins. They are used for internal signaling (PIN diode drive voltages). PCB EDGES The edges of the bottom circuit board have exposed inner layer traces (GND, VCC). Care must be taken such that they do not short to adjacent components.
