PMB2313T数据手册RF/IF射频/中频RFID的RFIC模块规格书PDF

描述 Description

Overview
Functional Description/ Application
This IC is designed for use in mobile radio communication devices up to 1100 MHz.
Due to low power consumption and low phase noise generation, the PMB2313T is suitable for use in battery powered handheld systems, e.g. GSM, cordless telephones and cordless consumer products, as well as in basestations.
Low supply voltage down to 2.7V. It can be switched to a low-power standby mode. Internal current source at the emitter follower output.
No external resistor needed in typical applications.
The divide ratio is 1:64/65 or 1:128/129 depending on the external circuit configuration.
The IC is board level compatible to the PMB 2312 prescaler.Circuit Description
The differential inputs of the IC may be connected either balanced or single ended. In the latter case the unused input must be RF-grounded with a capacitor (about 1.5 nF) with a low serial inductance.
Depending on the logic level at SW input the basic divide ratio of the ECL-stages is fixed to 1:64/65 or 1:128/129.
The MOD input determines whether modulus 1:n or 1:n+1 (n=64 or 128 according to SW-level) is active.
The IC can be switched to a low-power standby mode (input STB).
The MOD input is TTL/CMOS compatible.
The emitter follower output is CMOS compatible according to the application circuit on page 11. The minimum logic swing is 0.8 Vpp.
