Descriptions
The CMT2210LW is an ultra low-cost, low power, high
performance OOK stand-alone RF receiver for 315/433.92
MHz wireless applications. It is part of the CMOSTEK
NextGenRFTM family, which includes a complete line of
transmitters, receivers and transceivers. The CMT2210LW
is a true plug-and-run device, no register configuration and
manually-tune is required. The device operates at either
315 MHz or 433.92 MHz through selecting an 18.8744 MHz
or 26 MHz crystal, the data rate is optimized to around 2.4
ksps which fits well with the low-end data encoder or MCU
based transmitter. The CMT2210LW operates from 1.8 V to
3.6 V, finely work till the end of most batteries’ power. It
consumes 3.3 mA current while achieving -109 dBm
receiving sensitivity at 315 MHz and consumes 3.8 mA
current while achieving -108 dBm receiving sensitivity at
433.92 MHz. The SOP8 package is available for easier and
lower-cost manufacturing. The CMT2210LW receiver
together with the CMT211x transmitter enables an ultra low
cost RF link. For NextGenRFTM receivers with more
flexibility, the user can use the CMT2210AW.

Notes:
[1]. The CMT2210LW can directly work with external reference clock input to XIN pin (a coupling capacitor is required) with
peak-to-peak amplitude of 0.3 to 0.7 V.
[2]. This is the total tolerance including (1) initial tolerance, (2) crystal loading, (3) aging, and (4) temperature dependence.
The acceptable crystal tolerance depends on RF frequency and channel spacing/bandwidth.
[3]. This parameter is to a large degree crystal dependent.
