Product Specification PE42742 Product Description The PE42742 is an SPDT UltraCMOS™ Switch designed for Broadband applications such as CATV, DTV, Multi-Tuner DVR (Digital Video Recorder), Set-top Box, PCTV and Game Boxes. It meets FCC 15.115 spec of 80 dB isolation @ 216 MHz and offers high isolation and low insertion loss in both a powered and a unique unpowered default state. The PE42742 covers a broad frequency range from near DC to beyond 2200 MHz with a single positive supply and CMOS control. It provides a smaller, cost effective, more reliable and manufacturable alternative to mechanical relays in settop box applications. 75 Ω Terminated - 2200 MHz SPDT CATV UltraCMOS™ Switch Featuring Unpowered Operation Features • Meets FCC 15.115 spec of 80 dB isolation @ 216 MHz • Unpowered operational state • 2000 V HBM ESD tolerance, RF Pins • CTB performance of 90 dBc • High isolation: 63 dB at 1000 MHz • Low insertion loss: typically 0.5 dB at 5 MHz, 0.8 dB at 1000 MHz The PE42742 is manufactured on Peregrine’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.

Electrostatic Discharge (ESD) Precautions When handling this UltraCMOS™ device, observe the same precautions that you would use with other ESD-sensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOS™ devices are immune to latch-up. Switching Frequency The PE42742 has a maximum 25 kHz switching rate. ©2006 Peregrine Semiconductor Corp. All rights reserved. Page 3 of 11 PE42742 Product Specification Typical Applications Table 6. Truth Table VDD C1 (pin 17) C2 (pin 16) RFC – RF1 RFC – RF2 OFF Low Low ON OFF ON Low Low ON OFF ON Low High OFF ON ON High Low OFF ON ON High High ON OFF The PE42742 provides the high isolation required by FCC part 15.115 regulation between the television antenna and the cable plant. The advantage of the PE42742 is that device isolation / thru performance is maintained when power is removed. This unique feature makes the PE42742 ideal for set-top box and VCR applications. The PE42742 supports signal flow from RFC to RF1 and RF2 termination in the unpowered state; similar to the powered state with C1=C2 (both high or low). Note: A versatile logic table has been established to allow either C1 or C2 act as a single pin control and in either polarity. Figure 4.

The RF common port is connected through a 75 Ω transmission line to J2. Ports 1 and 2 are connected through 75 Ω transmission lines to J1 and J3. A through line connects F connectors J4 and J5. This transmission line can be used to estimate the PCB loss over the environmental conditions. J6 provides DC and digital inputs to the device. Figure 18. Evaluation Board Layouts Peregrine Specification 101/0269 The board is composed of a two metal layer FR4 material with a total thickness of 0.032”. The transmission lines are hybrid microstrip/coplanar waveguide with ground plane (28 mil core, 12 mil width, 12 mil gap). The provided jumpers short the control pins to ground for logic low. With the jumper removed the control input rises to VDD for logic high through the 1 MΩ pull up resistor. These resistors will draw several microamps from VDD. They are not required for normal operation. Figure 19. Evaluation Board Peregrine Specification 102/0352 ©2006 Peregrine Semiconductor Corp. All rights reserved.
