Epson launches 5G base station with high temperature resistance, high stability, and temperature compensated crystal oscillator TG7050SKN, etc

    Epson has launched six temperature compensated crystal oscillator models: TG7050CKN, TG7050SKN ，TG7050CMN，TG7050SMN ，TG-5510CA，TG-5511CA。 The characteristics of these models are high temperature resistance, with temperatures up to 105 ℃, and they are all high stability temperature compensated crystal oscillators, all of which are 7050 size. This size is usually applied to large high-end equipment such as industrial, automotive, communication, and network, and these models are also developed by the company for crystal oscillators used in 5G base stations. It can be widely applied to 5G base stations, microwave, network synchronization, BTS and other aspects. The characteristics of TCXO crystal oscillators TG7050CKN, TG7050SKN, TG7050CMN, TG7050SMN, TG-5510CA, TG-5511CA are not exactly the same. Below are the specific specifications:

Firstly, let me analyze the similarities between TG7050CKN, TG7050SKN, TG7050CMN, TG7050SMN, TG-5510CA, and TG-5511CA

These products are high stability TCXOs with CMOS or limited sine output

2. Provide a frequency range of 10~54MHz

The rated temperature of 3.5G base station and edge computing is+105 ℃, which requires outdoor installation, miniaturization and fanless operation

Compared with other temperature compensated crystal oscillators, it provides various improvements, such as low-temperature slope and phase noise

5. Compliant with GR-1244-COREStratum3 and G8262ECC-1 and ECC-2, without voltage control (Vc) function

Let's analyze the differences below. In fact, you can tell by looking at the model. TG7050CKN, TG7050SKN, TG7050CMN, TG7050SMN are one type, TG-5510CA, TG-5511CA are one type, as shown in the following figure:
