µPC1687G/GV
GENERAL PURPOSE 5 V FREQUENCY DOWN-CONVERTER IC
DESCRIPTION
The µPC1687 is Silicon monolithic IC designed for UHF band receiver applications. This IC consists of double
balanced mixer, local oscillator, IF amplifier, and voltage regulator.
The package is 8-pin SOP or SSOP suitable for high-density surface mount.
FEATURES
• UHF band operation
• Single-end push-pull IF amplifier suppresses fluctuation in output impedance.
• Good capability of UHF-varactor diode due to balanced amplifier oscillator
• Supply voltage: 5 V
• Packaged in 8-pin SOP or SSOP suitable for high-density mounting
APPLICATIONS
• Tuners for TV and VCR
• Receivers for UHF band

PIN EXPLANATION
Pin Symbol
No.
Function and Explanation
1 OSC base Internal oscillator consists in balance amplifier.
(bypass)
2 pin and 3 pin should be externally equiped
with tank resonater circuit in order to oscillate
with feedback loop.
2 OSC base 1 pin should be grounded through coupling
(feedback) capacitor to 5 pF.
3 pin is defined as open collector. This pin
should be coupled through resistor or chock coil
3 OSC
in order to adjust Q and be supplied voltage. In
collector
case of abnormal oscillation, adjust its Q lower
(coupling)
to stabilize the operation.
4 VCC
Supply voltage pin for the IC.
5 IF output IF output pin. IF amplifier is designed as single-
end push-pull amplifier.
This pin is assigned for the emitter follower
output with 50 constant resistive impedance
in wide band.
