achievable duty ratios. Push-pull currents are increased by
45 times their nominal values. The fixed time period is based
on the reference oscillator frequency f
T
, 10.9ms for f
T
=
6.00MHz, and varies inversely as f
T
varies.
Reference Oscillator
All timing and tuning operations on the MICRF007 are de-
rived from the internal Colpitts reference oscillator. Timing
and tuning is controlled through the REFOSC pin in one of two
ways:
1. Connect a crystal
2. Drive this pin with an external timing signal
The multiplication factor between the reference oscillator
frequency f
T
and the internal local oscillator (LO) is 64.5
×.
For
f
T
= f
LO
= 6.00MHz
×
64.5 = 387MHz.
The second approach is attractive for lowering system cost
further if an accurate reference signal exists elsewhere in the
system, for example, a reference clock from a crystal-con-
trolled microprocessor. An externally applied signal should
be ac-coupled and resistively-attenuated, or otherwise lim-
ited, to approximately 0.5Vpp. The specific reference fre-
quency required is related to the system transmit frequency.
Shutdown Function
The shutdown function is controlled by a logic state applied
to the SHUT pin. When V
SHUT
is high, the device goes into
low-power standby mode, consuming less than 1
μ
A. This pin
is pulled high internally. It must be externally pulled low to
enable the receiver.
