Product Specification PE4256 75 SPDT CATV UltraCMOS Switch 5 MHz3 GHz Product Description Features The PE4256 is an UltraCMOS Switch designed for CATV 75 characteristic impedance applications, covering a broad frequency range from 5 MHz up to Integrated 75 terminations 3 GHz. This single-supply SPDT switch integrates a two-pin CMOS control interface. It also provides low insertion loss with CTB performance of 90 dBc extremely low bias requirements while operating on a single 3- High isolation 65 dB at 1000 MHz volt supply. In a typical CATV application, the PE4256 provides Low insertion loss: typically 0.5 dB at for a cost effective and manufacturable solution when compared 5 MHz, 0.9 dB at 1000 MHz to mechanical relays. High input IP3: >50 dBm The PE4256 is manufactured on Peregrines UltraCMOS CMOS two-pin control process, a patented variation of silicon-on-insulator (SOI) Single +3 volt supply operation technology on a sapphire substrate, offering the performance Low current consumption: 8 A of GaAs with the economy and integration of conventional Unique all off terminated mode CMOS. 4 x 4 mm QFN package Figure 1.

Notes: 1. RF pins 3, 8, and 13 must be at 0 VDC. The RF pins do not require DC blocking capacitors for proper operation if the 0 VDC requirement is met. 2. Pins 16 and 17 are the CMOS controls that set the three operating states. 3. Connect pin 18 to GND to enable the on-chip negative voltage generator. Connect pin 18 to V (3V) to bypass and disable internal - SS 3V supply generator. 4. Customer can add external resistance to ground to change or modify termination resistance. 2010-2014 Peregrine Semiconductor Corp. All rights reserved.
