OB5269 is a highly integrated current mode PWM control IC with high voltage start up, optimized for high performance, low standby power consumption and cost effective offline flyback converter applications. Limitations include 1 kHz tuning resolution and no, the I/Q outputs aren't accessible, which is too bad I agree, no SSB or CW. Bulletin #1205111B_____W7206F2 Silicon Labs Bulletin rev AThe information contained in this document is PROPRIETARY to Silicon Laboratories, Inc. The radio also does a pretty decent job locking on to stations without a lot of drift problems especially in AM and FM mode. The hard wired 3" and 2" FSL Tecsun PL-380's work quite well, but the main drawback is that they require the very rare Russian surplus 100mm x 20mm x 3mm ferrite bars, which haven't been available commercially since 2012. Technically minded readers may be interested to know that two de-emphasis time constants are available within the Si4734-D60. The seller may be offering an improved version or it may be hanging out on the beach, enjoying the retired life.
Adesto introduces the Moneta™ RM3000 and RM3300 series product families; the world’s lowest power non-volatile memory. Si4735 ICs are the industry's first fully integrated, 100% CMOS AM/FM/SW/LW radio receivers., providing the space savings and low-power consumption necessary for portable devices, while delivering the high performance and design simplicity desired for all AM/FM/SW/LW solutions. We are your value added partner, reliable and informative inventory service for electronic components, discrete and integrated circuits. i've already designed my own Si4734-based receiver; that's now a matter of motivation. They claimed the AM section of this new model adopts an architecture similar to ATS909X, i.e. Connect the detachable AM antenna to enhance longwave and medium wave reception by simple rotating the antenna360 degrees until you find the best signal.
Mart’s FM Radio Antenna A simple antenna design for getting the most out of weak FM radio signals. PWM switching frequency at normal operation is internally fixed and is trimmed to a tight range.

It is applied to many fields, like Automotive Advanced driver assistance systems (ADAS) Industrial Factory automation & control Enterprise systems Data center & enterprise computing. It can highly improve on radio's sensitivity, selectivity, S/N ratio and anti-interference. Earlier I was collecting notes on which radio uses which chip (but is out of date now). Si4734 IC chip first converts the incoming signal from the antenna to a very low interThis - mediate frequency (IF).
I wanted the radio primarily for shortwave reception as I already have plenty of ways to listen to the standard AM/FM broadcast band, although the air band was intriguing as well. Si4734 ICs are the industry's first fully integrated, 100% CMOS AM/FM/SW/LW radio receivers., providing the space savings and low-power consumption necessary for portable devices, while delivering the high performance and design simplicity desired for all AM/FM/SW/LW solutions. I have this Si4703 evaluation board which I would like to modify to attach an external antenna. You'll find that link on just about every page in the Google eBookstore, so look for it at any time. These chips realises very wide band receiver (generally AM-SW-FM) without any conventional inductor and resonator but single chip controlled by I2C. One customer of my tindie store suggested me to check Si4720, and I was so surprised to see its function. It greatly improves the radio's sensitivity, selectivity, S/N ratio and anti-interference. It can highly improve on radio's sensitivity, selectivity, SIN ratio and anti-interference.
EU RoHS is "the European Directive 2011/65/EU on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic . Offering unmatched integration and PCB space savings, the Si4734/35 requires minimal external components and less than 20 mm2 of board area, excluding the antenna inputs. The real advantages of these DSP radios is simplicity of design and lower power compared traditional dual conversion analog radios.
The signal is then converted to a digital form for all subsequent signal processing using digital signal processing (DSP) techniques. It requires very few external parts to make it work, but does need some kind of microcontroller interfaced to it to operate it. Here are two video demonstrations: AM Band Scanning Click here to view on YouTube.
The board usually uses the plugged in headphone cable as the antenna.
There were a few goodies in the box too, a soft carry case, a pair of ear buds and a clip on wire antenna for improved reception on SW and VHF FM in very weak signal areas. Great Savings Free Delivery / Collection on many items AM/FM Portable Radios for sale | eBay Frequency modulation is used in a radio broadcast in the 88-108MHz VHF band. and shall not be reproduced or used inpart or whole without Silicon Laboratories’ written consent. I picked up a G3 after scouring reviews of every portable I could find in the sub-$120 price range. This page is a portal that describes the content of the SWLing.com family of websites.

In terms of price, the Si4737 chip starts at $3.06 in quantities of 10K; the Si4734/35 starts at $3.27 in quantities of 10K. When you enter your Landing home for the first time, youll notice the modern tones throughout, from the open concept floor-plan to the perfectly paired with the sleek kitchen with stainless steel appliances.
With unmatched integration and PCB space savings, Si4734/35 ICs require minimal external components and less than 20 mm² of board area, excluding the antenna inputs.

DigChip is a global services provider and solutions to suppliers and buyers for industrial and commercial electronic components. It seems that all the recent Tecsun SW radios are designed around the Silicone Labs DSP si4734 CMOS radio processor which is the magic behind its tremendous performance. This radio has highly improved sensitivity, selectivity, S/N ration and interference rejection.
Although the Si4734/35 will respond to only a single device address, this address can be changed with the SEN pin (note that the SEN pin is not used for signaling in 2-wire mode). You can get back to this and any other book at any time by clicking on the My Google eBooks link.
I'm also not sure if the frequency of the si4734 can be set outside the BC bands - maybe I ask for too much.
